Abstract

The invention discloses a coordinated optimization method and system for participation of an energy storage power station in multi-type peak regulation transaction. The coordinated optimization method comprises the following steps of: acquiring the optimal electric quantity of the energy storage power station participating in peak regulation auxiliary service transaction of different time scales through iterative calculation based on the transaction electricity price and transaction electricity of the energy storage power station by using a pre-constructed optimization model; and based on the optimal electric quantity of the energy storage power station participating in peak regulation auxiliary service transaction of different time scales, performing coordinated optimization on the energy storage power station participating in the peak regulation transaction, wherein the transaction power is determined based on a peak regulation auxiliary service transaction variety adopted by the energy storage power station, and the optimization model is constructed by taking the maximum daily net income of the energy storage power station as a target based on a relationship between the income of peak regulation auxiliary service transaction varieties of different time scales adopted by the energy storage power station and the daily penalty cost and the daily loss cost of the energy storage power station. According to the coordinated optimization method and the system, the optimal arrangement of different transaction varieties of the energy storage power station participating in the multi-time scale peak regulation auxiliary service is realized, the operation life of the energy storage power station is prolonged, and the overall income level of the energy storage power station is improved.

Description

technical field [0001] The invention relates to the field of power system energy storage, in particular to a coordination and optimization method and system for energy storage power stations participating in multi-type peak-shaving transactions. Background technique [0002] In order to ensure the safe and economical transmission of power from the power generation side to the user side, some services are provided by power generation, power grid or demand side resources, such as frequency regulation, voltage regulation, peak regulation, black start, etc. Peak shaving services can be divided into basic peak shaving services and paid peak shaving services. On the one hand, paid peak shaving refers to the deep peak shaving service provided by the generator set exceeding the specified peak shaving depth; Peak shaving service. At present, energy storage power stations can enter the peak-shaving auxiliary service market as an independent market entity, and peak-shaving auxiliary ...
