[0002] In the scenarios of emergency power supply and new energy consumption, active reserve is tight, flexible frequency regulation resources are scarce, the system is insufficient, and there are insufficient means of power balancing in emergency frequency regulation scenarios. Therefore, how to rationally utilize the "source-load-storage" multi-adjustable resources and maintain the operating adequacy of the new power system is very important for maintaining system power balance and frequency stability.

[0003] At the same time, the penetration rate of new energy sources continues to increase, and its volatility and uncertainty have brought huge challenges to the dispatching, operation and control of new power systems. With the continuous advancement of the construction of new power systems, the scale of distributed source, load and storage resources, represented by photovoltaics, electric vehicles, and energy storage stations, has grown rapidly. Among them, distributed power sources are easily affected by natural factors, have output fluctuations, and are intermittent; distributed loads have the characteristics of large differences in adjustable performance and limited single-point absorption capacity; distributed energy storage has the characteristics of wide geographical distribution and high cost. At present, various types of sources, loads, and storage resources are scattered, the control means are single, and there is a lack of intelligent and proactive coordinated control strategies, which makes it difficult to meet the requirements of "active" and "coordinated" frequency stability control.

[0083] In this optional embodiment, the access requirements of the source-load-storage multi-adjustable resources include: access mode, communication mode, communication protocol and control path.

[0084] In this optional embodiment, the multi-time-scale adjustable resource pool includes: a public communication mode and a fused local multimedia communication network communication mode.

[0085] In this optional embodiment, the source-load-storage multi-variable adjustable resource topology structure taking into account the adjustment characteristics includes: the source-side adjustable resources are in the form of wireless or optical fiber, and are connected to the corresponding communication network or user according to the voltage level; the load-side adjustable resources are adjusted and controlled by the load regulation system; the energy storage side adjustable resources are controlled by the monitoring system of the energy storage power station.

[0086] In this optional embodiment, the objective function of the comprehensive cost and regulation performance priority model includes: minimizing the comprehensive cost and maximizing the regulation performance; the comprehensive cost includes: the operating cost of conventional units, energy storage equipment, new energy, user load regulation cost and environmental cost; the regulation performance includes: adjustable capacity range, climbing rate, response time and regulation mileage.

[0087] In this optional embodiment, the constraints of the comprehensive cost and regulation performance priority model include unit operation constraints, unit climbing constraints, new energy unit output constraints, pumped storage operation constraints, electric energy storage operation constraints, various load-side resource constraints and power balance constraints.

[0088] In order to facilitate understanding of the above technical solutions of the present invention, the above technical solutions of the present invention are further described below from the perspective of architecture and principle, as follows:

[0089] Step 1: Analyze the regulation characteristics of different types of source, load and storage resources:

[0090] (1) On the source side, the adjustable resources on the source side mainly include thermal power units, hydropower units, wind power units, photovoltaic power stations, solar thermal power stations, nuclear power, etc. Taking thermal power units as an example, the adjustment ability of conventional units with flexible adjustment capabilities within a certain time scale is mainly determined by their inherent physical properties and current operating status. The adjustment mileage of the active output of the online unit at time t+τ can be written as:

[0091]

[0092] Where P G.t+τ represents the output of the thermal power unit at time t+τ, P G.t represents the output of the thermal power unit at time t, P G.max Indicates the upper limit of thermal power unit output and P G.min Indicates the lower limit of thermal power unit output; Indicates the maximum upward climbing rate of the online unit. It represents the maximum downward ramp rate of the online unit, and τ represents the time scale.

[0093] The flexibility of thermal power units often requires advance planning and scheduling to adapt to long-term changes in load demand; compared with conventional energy, changes in wind energy and photovoltaic energy are random, intermittent and volatile. The access of large-scale wind power will inevitably have a greater impact on the operation of the power grid; although the adjustable capacity of nuclear power plants is large, their one-time investment is large, and considering local specific conditions, they are not suitable for large-scale use; hydropower units have a fast adjustment rate, a wide range, and a low adjustment cost, and can be connected to the grid with intermittent power sources such as wind power and photovoltaics. As a supporting power source for the receiving load center, they can be given priority.

[0094] (2) The adjustable load on the load side refers to the load resources in the power system that have technical conditions and participate in the grid dispatching. The load side resources are mainly based on the demand response mechanism; the expressions for the adjustable mileage of interruptible load, transferable load after demand response, electric-cooling substitution load, and electric-heat substitution load are:

[0095]

[0096]

[0097] In the formula, represents the electric load after participating in the interruptible load demand response at time t, L e.t represents the conventional electricity load of the integrated energy hub at time t, represents the flexible supply of interruptible load at time t; represents the electric load after participating in the load transfer demand response at time t, represents the transferred power of the transferable load l at time t, represents the removed power of the transferable load l at time t; P AC.T represents the power of air-conditioning electric load that can be replaced by cooling load at time t, n represents the number of air-conditioners, and the opening time of the air-conditioner is τ on , τ c represents the control cycle of the air conditioner, P represents the average rated power of the air conditioner; τ represents the time scale, c represents the specific heat capacity of water, V t represents the volume of hot water used at time t, T t W represents the hot water temperature at time t, T c represents the cold water temperature, η WH Indicates the heating efficiency of the water heater, P WH.t It represents the power of water heater load that can be replaced by cooling load at time t.

[0098] The above four types of load-side flexibility resources participate in demand response in different ways, and thus the adjustment range of the resources that can be called upon also varies; the total amount of load-side flexibility resources is small, but its advantage is that the adjustment rate is very fast, and the response time of the maximum capacity can usually reach seconds.

[0099] 3. Energy storage side

[0100] Energy storage flexibility resources can be divided into electric energy storage systems and pumped storage power stations; the former specifically refers to battery energy storage, flywheel energy storage and compressed air energy storage; the regulation mileage expressions of electric energy storage systems and pumped storage power stations are:

[0101]

[0102]

[0103] Where P ES.t Represents the regulation mileage of the electric energy storage system, P PS.t represents the regulation mileage of the pumped storage power station, express, Indicates charging power. Indicates the energy release power, Indicates the maximum value of charging power. Indicates the maximum value of the energy release power, represents the upper limit of the storage capacity of the energy storage flexible resource e, represents the lower limit of the storage capacity of the energy storage flexible resource e, represents the charging efficiency of the energy storage flexible resource e, and represents the energy release efficiency of energy storage flexibility resources, Indicates the upward climbing rate of the pumped storage unit, Indicates the downward climbing rate of the pumped storage unit.

[0104] Energy storage batteries can respond to grid load fluctuations within milliseconds and quickly adjust power output to meet the instantaneous needs of the grid. They can be optimized and scheduled according to changes in grid load and prices. Compared with mechanical energy storage technologies such as pumped storage, energy storage batteries have a higher energy conversion efficiency and can achieve more precise power regulation. Battery energy storage can respond to grid load fluctuations within milliseconds, but the energy storage capacity of battery energy storage will gradually decrease with the increase in the number of charge and discharge cycles, so the service life is usually short, about 5-10 years.

[0105] Step 2: Establish a unified access and scheduling architecture for multiple adjustable resources including source, load and storage to achieve unified resource scheduling and management, and improve resource access efficiency and supply stability.

[0106] The unified access architecture of multiple adjustable resources such as source, load and storage Figure 3As shown, it includes three levels: network dispatching, provincial dispatching and local dispatching, which can realize cross-regional data interaction horizontally and information transmission at all levels vertically; the communication bus in this architecture should include reliable and general information interaction and wide area service mechanisms such as message bus / vertically, support safe and efficient data communication between load control systems at all levels, and horizontally, support safe and efficient data communication between load control systems and other business systems; it can support data sharing among nodes of various business applications through wide area service agent, message transmission mechanism and communication bus.

[0107] The unified access architecture of multiple adjustable resources of source, load and storage relies on automatic power control (APC) to complete control and regulation; it adopts information communication and automatic control technology, and issues real-time adjustment instructions by dispatching adjustable loads connected to lateral power plants, large industrial loads or aggregator platforms, so as to realize the target calculation, allocation and automatic tracking and adjustment of the active power of adjustable resources in each link of "source-load-storage" such as generators and adjustable loads within the power grid control range, so as to meet the requirements of real-time balance and frequency regulation of the power grid, and maintain the closed-loop control process of system frequency and interconnection line exchange power within the planned deviation range. It is a further deepening and expansion of the traditional automatic generation control (AGC) function.

[0108] Step 3: Consider the communication delay and control requirements when accessing resources, and determine the access method, communication method and communication protocol of the source, load and storage multi-adjustable resources.

[0109] Aiming at the information interaction needs of the coordinated interactive business of distributed source, load and storage resources, combined with the selection analysis of communication technology, the remote communication network based on public communication methods such as 4G / 5G and wireless base stations and the local multi-media communication network integrating multiple communication methods such as RS485, high-speed power line communication (HPLC), high-speed radio frequency (HRF), Zigbee, WiFi, and optical fiber are used to support the aggregation of distributed resources to form a multi-time scale adjustable resource pool, and then participate in the precise control of the power grid; based on the unified access dispatching architecture and communication technology characteristics of the above-mentioned source, load and storage multi-adjustable resources, the communication mode and access scheme of the source, load and storage multi-adjustable resources under different voltage levels are designed, as follows:

[0110] (1) 10kV / 35kV voltage level

[0111] Source, load and storage resources are connected to the grid dispatching center through 4G / 5G public network and optical fiber communication. The high-voltage level equipment of source, load and storage resources is directly connected to the dispatching center, distribution electrification master station and smart energy service platform of the grid layer through the remote communication network composed of EPON optical communication network and 4G / 5G public network, completing the APC adjustment instructions, dispatching plan, demand response instructions and other typical distributed resource interactive business information interaction. The access architecture is as follows Figure 4 shown.

[0112] (2) 220V / 380V voltage level
