Power Regulation Method for Grid Connected Distributed Photovoltaic Power Generation Based on Collaborative Division of Power Generation Clusters
The smooth operation of grid connected distributed photovoltaic power generation is crucial.In order to reduce the impact of power fluctuations on the grid frequency,this study designed a distributed photovoltaic power generation grid connected power regulation method based on the collaborative division of power generation clusters.First of all,based on the construction of a distributed photovoltaic power generation model,its power output characteristics are analyzed,and the maximum output power point is tracked.Then,the photovoltaic power generation cluster is dynamically divided based on the coordination algorithm,and the reactive power regulation and active power regulation range are calculated.Finally,on the basis of the smooth fluctuation of photovoltaic power,the grid connected system frequency modulation energy storage capacity is planned,then a distributed photovoltaic power generation grid connected power regulation model to suppress the power circulation problem between the battery energy storage systems,and power regulation is achieved.According to the simulation experiment,this method can effectively control the grid connected photovoltaic power generation under three typical weather conditions.After a fault occurs in the grid connected system,this method can quickly respond to the regulation in a short time and complete the power balance regulation.
