含分布式光伏发电的中压配电网电压控制策略
Voltage control strategy for medium voltage distribution network with distributed photovoltaic generators
With the increasing scale of grid-connected distributed photovoltaic power generation system, the problem of voltage violation, which is resulted from the reverse power flow due to the imbalance between power and load, is a matter of great concern. On the basis of analyzing voltage and active / reactive voltage regulation of photovoltaic access points, the reactive / active coordinated control strategy is proposed. The node voltage is controlled through compensating the reactive output compensation of photovoltaic inverter and optimizing photovoltaic power generation. The simulation results show that the strategy can solve the problem of voltage violation in the distribution network of distributed photovoltaic generators while taking the efficiency and economy of photovoltaic utilization into account.
