Description

Technical Field

[0001] This disclosure generally relates to the field of shore power dispatching technology, and specifically to a method, device, equipment and medium for intelligent dispatching of shore power in ports. Background Technology

[0002] Shore power, a term published in 1996 in the field of marine science and technology, refers to the method of supplying electricity to ships while they are berthed, replacing diesel generators with access to the land-based power grid. This includes both high-voltage and low-voltage shore power systems. Driven by the global green transformation of ports and the "dual carbon" goal, shore power technology, with its advantages of "replacing oil with electricity" and reducing pollution emissions from ships berthing, has become a core technological path for energy conservation and emission reduction in ports. Transmitting electricity from the land-based power grid to ships to replace diesel generators not only significantly reduces emissions of pollutants such as sulfur oxides and nitrogen oxides but also reduces port noise pollution, offering significant environmental and social benefits and serving as a key measure for achieving sustainable port development.

[0003] Ship departure is a critical juncture for the stability of the shore power system and requires close attention. Before departure, ships need to gradually reduce their shore power supply and switch to marine generators. This transition must be smooth to avoid impacting ship equipment and the port's power grid. Furthermore, the power fluctuations of departing ships affect the overall load balance of the port. Therefore, how to smoothly manage the power supply connection for departing ships is a pressing issue that needs to be addressed. Summary of the Invention

The relevant data can only be obtained after the user's authorization and permission, and the acquisition or use of the data complies with the laws and regulations of the relevant regions.

[0045] Please refer to Figure 1 , Figure 1 A flowchart illustrating a port shore power intelligent scheduling method according to an embodiment of this application is shown. Figure 1 As shown, the method includes:

[0046] Step 101: Obtain the departure plans of berthed vessels and identify at least one vessel to depart.

[0047] It should be noted that a port is a transportation hub located along the coast of the sea, rivers, lakes, or reservoirs, possessing the facilities and conditions for multimodal transport connecting the sea and land to ensure the safe entry, exit, and berthing of ships. Ports are the convergence and hub of water and land transportation, distribution centers for industrial and agricultural products and foreign trade import and export goods, and places for ships to berth, load and unload cargo, embark and disembark passengers, and replenish supplies. A berth is the basic unit of port loading and unloading operations, usually divided along the wharf line; a berth is defined as long enough to berth one ship. Ship berths are classified in many ways, such as their function, wharf structure, water depth, and geographical location; different types of berths correspond to different ship needs and operational scenarios. The Terminal Operating System (TOS) is a computer management system used to manage and control all aspects of wharf operations. It mainly includes ship planning, yard control, ship loading and unloading control, inspection bridges, billing, and acceptance, and is the center of wharf production management.

[0048] In other words, once a vessel enters the port and is moored at its berth, it submits a departure plan through the terminal operating system (TOS). The electrical system can then obtain the departure plans of the moored vessels through the TOS and identify at least one vessel awaiting departure.

[0049] Among them, vessels awaiting departure are those whose departure is scheduled to take place within a predetermined time period in the future, such as two hours later.

[0050] Step 102: For each vessel waiting to depart, generate the corresponding departure phased power demand curve.

[0051] It should be noted that the power switchover for a vessel departing from port involves multiple stages, including a steady-state operation stage, a load reduction stage, a vessel engine startup stage, and a power transfer stage. The steady-state operation stage is when the vessel is normally and stably powered by shore power; the complete execution sequence for the departure switchover begins at this stage. The load reduction stage involves the gradual shutdown of non-critical loads, resulting in a decrease in power demand. The vessel engine startup stage involves the startup of auxiliary marine machinery, which synchronizes with shore power to supply power to the vessel. The power transfer stage involves the transfer of power from shore power to the vessel engines, with shore power decreasing to zero and the cables being disconnected.

[0052] It should be understood that the port shore power grid is a relatively independent, weak grid or end-point network, highly sensitive to power fluctuations. Unlike an infinite power grid, the port's internal shore power distribution network (especially the busbars on the high-voltage frequency converter output side) has relatively limited short-circuit capacity and a relatively large system equivalent impedance. When the total active power at the connection point changes rapidly and significantly, it will cause obvious voltage fluctuations and frequency deviations. For example, when a large container ship departs, its power demand may drop from 6 MW to 0 MW within 30 minutes, meaning that the power "drawn away" from the port grid is reduced by 6 MW in a short period of time. Therefore, power dispatching is needed to ensure a smooth transition of the shore power grid when ships depart.

[0053] In one specific embodiment, for each vessel awaiting departure, at least one critical load, interruptible load, and adjustable load of the vessel are obtained; according to the departure plan of the vessel, the shutdown function corresponding to the interruptible load and the adjustment function corresponding to the adjustable load are obtained respectively, and the shutdown function and the adjustment function correspond to multiple power switching processes in the departure plan; based on the critical load, interruptible load, adjustable load, and the shutdown function corresponding to the interruptible load and the adjustment function corresponding to the adjustment load, the departure phased power demand curve corresponding to the vessel is generated.

[0054] Critical loads refer to equipment that ensures the safety and continuity of a ship's departure operations, such as navigation radar, Very High Frequency (VHF) communication, gyrocompass, emergency lighting, and the necessary steering gear. Interruptible loads are non-critical equipment whose temporary shutdown will not affect the ship's departure safety and core operations, such as some living quarters' air conditioning, dining facilities, and entertainment systems. Adjustable loads are equipment whose power can be dynamically adjusted according to the operational phase, such as ballast pumps and cargo securing equipment that are still in operation. The shutdown function describes the planned shutdown process of interruptible loads during the departure preparation phase. The adjustment function describes the power level changes of adjustable loads during the departure process.

[0055] It should be understood that the shutdown function simulates the proactive operation of reducing the ship's total power demand. Before the ship departs, the crew will gradually shut down non-essential equipment according to a checklist to prepare for subsequent engine startup and power switching. Quantifying this process using the shutdown function during the analysis allows for a more accurate prediction of the trajectory of the ship's power demand decline, thus enabling advance planning of the shore power transfer curve and preventing the shore power decline from being too rapid or too slow. The regulation function reflects the dynamics and uncertainties of the ship's departure operation. Unlike the shutdown function, the power change of the regulation load is not necessarily monotonically decreasing and may fluctuate according to the progress of the operation.

[0056] For example, the phased power demand curve for departure can be expressed as follows:

[0057]

[0058] in, This represents the power demand for ships departing from port, used to describe the power demand curves at different stages of departure. The base power of the critical load c. Let be the state function of the critical load c at time t. For the critical load set, The base power of interruptible load i. Let i be the shutdown function of the interruptible load i at time t. For interruptible load sets, The base power of adjustable load a, Let a be the adjustment function of the adjustable load a at time t. It is an adjustable load set.

[0059] It should be understood that the state function of the critical load c at time t The value is always 1 to characterize the absolute power supply continuity requirement of critical loads, meaning that shore power systems and ship power systems must supply power to these loads seamlessly and uninterruptedly.

[0060] The turn-off function can be further expressed as:

[0061]

[0062] in, This is the start time for the departure handover of vessels waiting to depart. For departure schedule, This refers to the timeframe for the stable operation phase corresponding to the departure plan. This refers to the timeframe for the load reduction phase corresponding to the departure plan. This refers to the timeframes for the ship's engine start-up and power transfer phases corresponding to the departure plan.

[0063] In other words, the shutdown function has obvious temporal and phased characteristics. During the steady-state operation phase, all interruptible loads operate normally. During the load reduction phase, the loads are gradually shut down according to the plan, which is a linear decrease. During the engine start-up phase and the power transfer phase, the loads are completely shut down.

[0064] It should be understood that the adjustment function is also related to multiple phases of the departure plan, and is adjusted in stages according to the operational requirements of the adjustable load. This application does not impose specific limitations on it.

[0065] Therefore, this embodiment constructs a phased power demand curve for departure by combining key loads and state functions, interruptible loads and shutdown functions, and adjustable loads and adjustment functions. The state function defines the minimum demand for ship departure, the shutdown function defines the downward trend of demand, and the adjustment function defines the dynamic fluctuation of demand. The combination of these three functions transforms the ship departure power demand from the traditional "rated power" into a time-varying power demand curve that reflects the actual operation process, facilitating coordinated control of other ships in port based on the power changes of departing vessels.

[0066] Step 103: Generate a collaborative scheduling scheme for other vessels in port based on the power demand curve.

[0067] It should be noted that the coordinated scheduling plan for other vessels in port refers to the power adjustment plan for other vessels in port at various times during the departure phase of the vessels waiting to depart, including but not limited to power increase, power decrease, and power unchanged.

[0068] Specifically, based on the phased departure power curves, the shore power transfer curves corresponding to the vessels to be departed are determined; based on the shore power transfer curves, a multi-vessel collaborative power compensation objective function is constructed; the multi-vessel collaborative power compensation objective function includes the power adjustment amounts of other vessels; based on the power adjustment amounts of other vessels at each time point, a collaborative scheduling scheme for other vessels is generated.

[0069] It should be noted that the shore power transfer curve is the minimum power curve that needs to be transferred to other vessels during the departure phase of a vessel waiting to depart. Specifically, the shore power transfer curve is the difference between the power demand curve of the vessel waiting to depart in each stage of departure, starting from the vessel's engine startup phase, and the power supplied by the vessel. In a preferred embodiment, the shore power transfer curve is the difference between the power demand curve of the vessel waiting to depart in each stage of departure, starting from the vessel's engine startup phase, and the power supplied by the vessel and the allowable fluctuation of shore power.

[0070] In other words, after determining the power demand of the vessel waiting to depart at each moment during the departure phase, the power demand of the vessel waiting to depart is gradually transferred to the ship's power supply. In this process, the difference between the gradually transferred demand change and the allowable fluctuation of shore power is used as the amount of power transfer that needs to be adjusted to other vessels.

[0071] Furthermore, based on the shore power transfer curve, a multi-ship collaborative power compensation objective function is constructed to compensate for grid fluctuations caused by the power reduction of ships waiting to depart by adjusting the power of other ships in port.

[0072] In a feasible embodiment, a shore power fluctuation term is constructed based on the shore power transfer curve; an adjustment magnitude term for other ships is constructed based on their base power and power adjustment amount before adjustment; an equipment switching term is constructed based on the power adjustment amount at each time point; and a multi-ship collaborative power compensation objective function is constructed based on the shore power fluctuation term, the adjustment magnitude term, and the equipment switching term.

[0073] For example, the objective function for multi-ship cooperative power compensation can be expressed as follows:

[0074]

[0075] in, and To adjust the start time and the departure switch start time of vessels waiting to depart, Let be the amount of shore power transferred at time t. For assembling other vessels in port at their berths, Let be the power adjustment amount of berth j at time t. This represents the base power of berth j before adjustment. The number of ships that need to be significantly adjusted at time t. , and These are the weighting coefficients.

[0076] Among them, the adjustment magnitude term determines the relative adjustment amount of each berth by the power adjustment amount of berth j at time t and the base power of berth j before adjustment. In the process of solving the objective function, it can effectively avoid causing excessive impact on the power consumption of other ships.

[0077] It should be understood that, in the embodiments of this application, since the departure of a ship has a certain time phase, there may be a situation of ship alternation at other berths. For example, a new ship may enter berth j during the departure phase of a ship waiting to depart. Therefore, the objective function uses the berth as a reference object to adjust the power to adapt to the power adjustment changes of each port and berth within the complete departure plan.

[0078] It should also be understood that, in the embodiments of this application, the parameter expressions in the objective function are used to characterize the corresponding attribute information, and those skilled in the art can perform normalization processing when applying them in order to unify the dimensions.

[0079] In one feasible embodiment, the power adjustment amount is allocated according to the priority of each other vessel in port.

[0080] Specifically, the power adjustment amount for each berth at time t can be determined using the following formula:

[0081]

[0082] in, Let be the power adjustment amount of berth j at time t. For the priority of the vessel corresponding to berth j, Let t be the total power adjustment at time t.

[0083] It should be understood that the denominator in the power adjustment allocation formula is used to calculate the total adjustment acceptance rate of other vessels in port, that is, to allocate the total adjustment amount according to the proportion of the inverse of the priority weight of each berth. The larger the value, the lower the ship's willingness to adjust (the higher the priority), and therefore the smaller the adjustment amount allocated to it.

[0084] In another feasible embodiment, the number of ships requiring significant equipment adjustments can be determined using the following formula:

[0085]

[0086] in, The number of ships that need to be significantly adjusted at time t. Let be the power adjustment amount of berth j at time t. This is the power adjustment threshold.

[0087] In other words, this application determines other vessels whose power adjustment amount exceeds the power adjustment threshold as vessels that require significant adjustments by setting a power adjustment threshold.

[0088] It should be understood that, in the embodiments of this application, by constructing an objective function, the power consumption of other ships in port can be adjusted step by step during the departure phase of the ship waiting to depart. The minimum value of the adjustment range term and the equipment switching term is obtained so that the adjustment scheme calculated according to the objective function can minimize the power adjustment of other ships in port, effectively reduce the number of ships that need to be significantly adjusted, and reduce the equipment wear and tear on other ships in port.

[0089] In a preferred embodiment, a port may have multiple vessels waiting to depart simultaneously. By analyzing the departure phase power demand curve of each vessel waiting to depart, the total departure phase power demand curve of the multiple vessels waiting to depart at each time is determined. Then, based on the total departure phase power demand curve, the total shore power transfer curve corresponding to the shore power network is determined. Based on the total shore power transfer curve, a multi-vessel collaborative power compensation objective function is constructed to adjust the power transfer of multiple berths and multiple departing vessels in the port.

[0090] Therefore, this application's embodiment analyzes the shore power transfer curve corresponding to the departing vessel and constructs a multi-vessel collaborative power compensation objective function. This achieves a smooth transition of the entire shore power grid through global, refined scheduling of the single-point large disturbance of vessel departure, effectively ensuring the safe and high-quality operation of the multi-berth shore power system. Compared to traditional disturbance handling based on model prediction, the phased analysis of the departing vessel's power demand makes the power change curve more closely match the physical process of vessel departure, resulting in a more realistic adjustment scheme rather than a simple "prediction." The objective function construction has higher interpretability, ensuring that the optimization results of the objective function have higher operability.

[0091] Step 104: According to the collaborative scheduling plan, conduct power dispatch for other vessels in port.

[0092] Specifically, during the departure process of a vessel waiting to leave port, the power of other vessels is adjusted according to the power adjustment amount of other vessels in port at each moment in the collaborative scheduling plan.

[0093] In summary, the port shore power intelligent scheduling method provided in this application obtains the departure plans of berthed vessels, identifies at least one vessel to depart, generates a phased departure power demand curve for each vessel, and generates a collaborative scheduling scheme for other vessels in port based on the phased departure power demand curve. According to the collaborative scheduling scheme, power scheduling is performed on other vessels in port, thereby transforming the single-point large disturbance of vessel departure into a smooth transition of the entire shore power grid through global fine-grained scheduling, thus effectively ensuring the safe and high-quality operation of the multi-berth shore power system.
