Abstract

A long-term scale voltage optimization control strategy for distributed photovoltaic actively participated with distribution network considering active reduction is proposed. The residual capacity of PV inverters outside the active power is used to participate in the reactive power optimization for voltage control. If the voltage still exceeds the threshold values, the active power curtailment strategy to PVs is applied to provide more capacity for reactive power optimization and maintain the voltage in range. Considering the uncertainties of photovoltaics and load outputs, the complex affine method is employed to establish the power output model in each time period. Combination of the Ybus power flow calculation and the linear decreasing weight particle swarm optimization is used to solve the proposed optimization model. Case studies on an IEEE 33-bus system are conducted to verify the effectiveness of the proposed optimization strategy.
