Abstract

A large-scale energy storage power station peak shaving controller and method based on ANFIS short-term load prediction, the controller includes a peak shaving control master station module and an energy storage sub-station module connected to it, and the peak shaving control master station module includes floating point arithmetic processing controller, FPGA processor, CAN communication interface, power module, display module, RAM memory, scheduling network port and buttons, floating-point arithmetic processor is connected to FPGA processor, CAN communication interface and buttons are connected to floating-point arithmetic processor, and power module is connected The floating-point arithmetic processor and FPGA processor, display module, RAM memory and dispatching network port are all connected to the FPGA processor; it can evaluate the comprehensive charge level of the energy storage power station in real time, predict the load of the regional power grid, and coordinate and control multiple power stations in the power station. The charging and discharging power of the energy storage battery can be used to give full play to the fast and flexible power throughput of large-scale energy storage power stations, and participate in the peak load shaving and valley filling of the power grid, which can effectively relieve the pressure of peak regulation. At the same time, optimize the charge level of the energy storage battery, avoid overcharging and overdischarging, and prolong the battery life.

Description

Technical field: [0001] The invention relates to a peak-shaving controller of a large-scale energy storage power station based on ANFIS short-term load forecasting and a control method thereof. Background technique [0002] Due to environmental pressure, the installed capacity of intermittent and fluctuating new energy generation such as photovoltaics and wind power has continued to expand in recent years, and the power grid is facing unprecedented pressure for peak regulation. In order to ensure the balance of power supply and demand and improve the stability and reliability of power supply, more effective peak regulation measures must be taken. Traditional peak shaving generally adopts thermal power peak shaving and hydropower peak shaving, etc. These supply-side adjustments are costly and difficult to implement. Large-scale battery energy storage systems can achieve fast and flexible power throughput, which can meet the needs of power grid peak shaving and valley filling....
