Abstract

This application provides a network-load-storage demand response control system and a control method. The network-load-storage demand response control system includes a controller, a PCS and a BMS communicating with the controller, and a load-side electric meter and a grid-side electric meter connected to the controller. , grid circuit breaker, load circuit breaker and grid contactor; BMS is used to obtain the SOC of the energy storage battery and send it to the controller; the load-side ammeter is used to obtain the real-time power of the load, and the grid-side ammeter is used to obtain the voltage of the grid , the grid circuit breaker is used to send the status signal of the grid circuit breaker to the controller, the load circuit breaker is used to send the status signal of the load circuit breaker to the controller, and the grid contactor is used to send the status signal of the grid contactor to the controller ; The controller is used to control the output power of the PCS to control the charging and discharging of the energy storage battery. The application can fully control the demand response of the power grid, the load and the energy storage battery under the condition that the power supply demand of the load is met.

Description

technical field [0001] The application belongs to the technical field of energy storage, and in particular relates to a network load storage demand response control system and a control method. Background technique [0002] The energy storage power station system is a system that uses electrochemical batteries for electrical energy storage and can be connected to the municipal grid. The application of large-capacity battery energy storage in power systems has a history of more than 20 years. With the rapid development of wind power, photovoltaic and other new energy industries, the development of large-capacity energy storage industry is accelerating. After the power energy storage system is introduced into the power system, it can not only improve the stability of the power system, but also serve as a new means of adjusting frequency, compensating power, improving power quality, compensating for load fluctuations, shifting peaks and filling valleys, and increasing power dem...
