[0043] Embodiments of the present application are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present application, and should not be construed as limiting the present application.

[0044] The installed capacity of photovoltaic power in the current power system is getting larger and larger, and the proportion of installed capacity is increasing. The traditional power system is transforming into a new power system - with the main task of maximizing the consumption of new energy, supported by the interaction of source, grid, load and storage and multi-energy complementarity. Hydropower complementarity is a major form in the new power system. Hydropower complementarity is to connect the photovoltaic station to the hydropower station, connect to the power grid through the transmission channel of the hydropower station, and use the regulation and storage capacity of the hydropower station reservoir and the rapid regulation capacity of the hydropower unit to bundle and send the photovoltaic power generation and hydropower unit power together to improve the utilization rate of the transmission line channel. Hydropower complementarity mainly utilizes the seasonal characteristics of the reservoir, which is divided into the flood season and the dry season. During the flood season, the hydropower unit outputs according to the incoming water and system demand, fully consumes the reservoir capacity, and the photovoltaic output tracks the hydropower output to increase the short-term peak capacity of hydropower; during the dry season, the hydropower will give way to the photovoltaic output, and the photovoltaic output is not limited. The hydropower unit plays the characteristics of flexible start and stop, providing peak and frequency regulation capacity for the system and photovoltaic.

[0045] However, in the prior art, hydropower stations and photovoltaic power stations are usually operated independently, failing to fully utilize the complementarity between the two. In addition, the operation of the power station usually does not take into account the optimization of load fluctuations and water consumption, resulting in low energy efficiency and waste of resources.

[0046] To address this problem, the present invention provides a method for optimizing a water-photovoltaic complementary model to improve water energy storage efficiency. Figure 1 A schematic diagram of a flow chart of a water-photovoltaic complementary model optimization method for improving water energy storage efficiency provided in an embodiment of the present application. Figure 1 As shown, the method comprises the following steps:

[0047] Step 101, determining the application scenario of the water-light complementary model.

[0048] In a possible embodiment, the application scenario of the water-light complementary model is as follows: Figure 2 shown.

[0049] exist Figure 2 The scenario shown includes four hydropower units and three photovoltaic stations, including:

[0050] The installed capacity of the first hydropower unit 1F, the second hydropower unit 2F, and the third hydropower unit 3F are all 250MW, and the installed capacity of the fourth hydropower unit 4F is 120MW;

[0051] The installed capacity of the first photovoltaic station 1G is 28MW, the installed capacity of the second photovoltaic station 2G is 78MW, and the installed capacity of the third photovoltaic station 3G is 425MW;

[0052] On the premise of meeting the load demand of 220kV line, the second photovoltaic station 2G, the third photovoltaic station 3G, the third hydropower unit 3F and the fourth hydropower unit 4F, the excess load is boosted from the interconnecting transformer 5G and sent out through the 500kV line. The first hydropower unit 1F, the second hydropower unit 2F and the first photovoltaic station 1G meet the 500kV load demand.

[0053] The symbol parameters involved in this application scenario are shown in the following table.

[0054] Table 1

[0055]

[0056]

[0057] Step 102, in the application scenario, under the premise of ensuring that photovoltaic power generation is fully generated, the output of each hydropower unit is adjusted to meet the load demand of the 500kV line and the 220kV line, and the objective function is constructed with the goal of minimizing the total water consumption of all hydropower units.

[0058] In the embodiment of the present application, under the premise of meeting the system load demand, meeting the forced output of hydropower, and ensuring that photovoltaic power generation is fully generated, the load demand of the 500kV line and the 220kV line is met by adjusting the output of 1F-4F. On this basis, the output of 1F-4F is reasonably arranged to achieve the goal of minimizing the total water consumption.

[0059] Among them, the objective function constructed with the minimum total water consumption of all hydropower units can be expressed as:

[0060] minH=aP1+bP2+cP3+dP4

[0061] Among them, H is the total water consumption of all hydropower units, a, b, c, d are the water consumption rates of the first, second, third and fourth hydropower units respectively, and P2, P2, P3, P4 are the real-time powers of the first, second, third and fourth hydropower units respectively.

[0062] In a possible embodiment, [a bcd] = [0.20.250.220.6].

[0063] Step 103, determining boundary conditions according to the stable operation areas and vibration areas of different hydropower units, solving the objective function under the constraints of the boundary conditions, and obtaining the optimal scheduling solution.

[0064] In a possible embodiment, it is assumed that 1F and 2F are in a stable operation zone in the 0-250MW load range; 3F is in a vibration zone in the 40-140MW load range, and the unit should not be operated in this load range, and the 0-40MW and 140-250MW load ranges are in a stable operation zone, and the unit can be operated stably for a long time in this load range; 4F is in a vibration zone in the 10-90MW load range, and the unit should not be operated in this load range, and the 0-10MW and 90-120MW load ranges are in a stable operation zone, and the unit can be operated stably for a long time in this load range. The above boundary conditions are as follows:

[0065]

[0066] Among them, P 1G , P 2G , P 3G are the real-time power of the first photovoltaic station, the second photovoltaic station, and the third photovoltaic station, P 220 is the real-time power of 220kV line, P 500 is the real-time power of the 500kV line.

[0067] It can be understood that after determining the constraints and the objective function, solving the model is well known to those skilled in the art, and this application does not specifically limit the solution method.

[0068] As an implementation method, use linear programming, nonlinear programming or other optimization algorithms to solve the model, and consider using tools such as MATLAB and Python for numerical simulation and optimization.

[0069] It can be understood that the water-photovoltaic complementary model proposed in this application uses a connecting transformer to connect the three voltage levels of 500kV, 220kV, and 35kV. Photovoltaic stations are connected to the three voltage level buses, which is generally representative of the water-photovoltaic complementary mode. Moreover, most photovoltaic stations are currently connected to hydropower stations at a single voltage level. Therefore, the actual part of the model can be extracted to establish a model and solve it.

[0070] Step 104: Adjust the output of each hydropower unit based on the optimal scheduling plan.

[0071] In a possible embodiment, after adjusting the output of each hydropower unit based on the optimal scheduling scheme, the single-day output curve obtained by MATLAB simulation is as follows: Figure 3 shown.

[0072] It can be understood that the water-photovoltaic complementary operation model proposed in this application has the following effects:

[0073] 1. Hydropower and photovoltaic complementary peak-shifting power generation enhances peak capacity. In the hydropower and photovoltaic complementary model, photovoltaic output increases during the day, hydropower output decreases under normal circumstances, and reservoirs store water; during peak electricity consumption periods, hydropower increases its output, forming a reasonable staggered system demand for photovoltaic and hydropower output.

[0074] 2. "Store water in low seasons and consume water in high seasons" on an annual scale to effectively optimize the energy structure of the power grid. The water inflow of hydropower is divided into the flood season and the dry season. In the flood season, the upstream water inflow is large. In order to avoid water abandonment, a certain hydropower output needs to be guaranteed. During the flood season, when the sunlight is good and the channel capacity is limited, the hydropower units reduce the output to give up the channel and form a short-term water storage, giving priority to photovoltaic power generation. The hydropower units adjust the output according to the needs of the system, and the hydropower output tracks the photovoltaic output during the day. When the sunlight is not ideal, the hydropower output is increased according to the water inflow and system needs to fully absorb the reservoir capacity; during the dry season, the upstream water inflow is small. While ensuring the minimum forced output of hydropower, the delivery channel can be given to photovoltaic power generation as much as possible, and the reservoir can store water. The hydropower units play the characteristics of flexible start and stop, providing peak and frequency regulation capacity for the system and new energy.

[0075] 3. Hydropower regulation can smooth out the fluctuation of new energy load on a daily scale. Photovoltaic power generation has the obvious characteristics of large installed capacity and small power output, and is easily affected by weather, temperature, solar radiation intensity, etc. For the problem of large fluctuations in photovoltaic output during the day, the hydropower regulation capacity in water-photovoltaic complementarity can be fully utilized to smooth it out. The rapid and flexible response capabilities of hydropower units can cope with extreme situations such as instantaneous decline in photovoltaic output caused by extreme weather and partial photovoltaic matrix disconnection caused by collector line failure.

[0076] 4. The regulation characteristics of hydropower units strongly support the consumption of new energy. The water-photovoltaic complementary operation model is photovoltaic power to hydropower power. As a large power source, the hydropower unit has the characteristics of rapid regulation and can provide effective frequency regulation technology support for the surrounding photovoltaic power generation operation. At the same time, the power-to-power characteristics of the water-photovoltaic complementary model, through the rotating standby of the hydropower unit, the response of the synchronous generator is increased, providing regional inertia response capability.

[0077] In order to implement the above-mentioned embodiments, the present application also proposes a water-photovoltaic complementary model optimization device for improving water energy storage efficiency.
