一种适用于黑启动的光储联合发电系统协调控制策略
A Coordinated Control Strategy of PV Battery-Energy Storage Hybrid Power System for Black Start
摘要
Abstract
In order to study black starting capacity of hybrid PV battery-energy-storage power system, this paper simulates black start process with method of starting asynchronous motor for electric power plant under island operating condition. Hybrid PV battery-energy-storage system model and control system are established. As main power supply, energy storage utilizes V/f control to smooth PV power fluctuations to maintain stability of system voltage and frequency. Considering black start failure due to insufficient charge capacity, this paper proposes a new method combining load tracking and conventional maximum power point tracking (MPPT) based on MPPT algorithm, making PV system effectively tracking load change when PV has sufficient output, thus no surplus power is charged to energy storage. The PV system can track maximum output power and supply for the load together with energy storage when PV has insufficient output, thereby reducing energy storage capacity requirements. Simulation results verify feasibility and correctness of the proposed control strategy and ability to provide black start power for restoration of large power grids and fast black start capability of hybrid PV battery-energy storage power system.关键词
