摘要
针对水光储柴独立混合型微电网的运行需求,分析了光储在该混合微电网中稳态和暂态时的特性,分别提出了稳态控制策略和暂态控制策略。通过搭建水光储柴微电网模型,对提出的光储协调控制策略进行了实时数字仿真(RTDS,real time digital simulation)。经过现场实验,验证了微网中控制策略的可行性和可靠性。
In view of the demand of hydro-PV-storage-diesel hybrid micro-grid,the steady state characteristics of PV-storage system in mixed micro-grid are analyzed,and the control strategy is proposed.At the same time,the transient state characteristics of PV-storage system in hybrid micro-grid are also analyzed,and the transient state control strategy is proposed.Then,the proposed coordination control strategy is simulated by RTDS after building the hydro-PV-storage-diesel hybrid microgrid model.Finally,it is verified that the control strategy of PV-storage system is feasible and reliable through related experiments.
