A flexible interconnection control optimization method for an ac-dc hybrid power distribution network

Abstract

The present application relates to the technical field of power distribution network operation control, in particular to a flexible interconnection control optimization method for AC-DC hybrid power distribution network. The method solves the technical problem that the prior art lacks a collaborative control mechanism for overall linkage of multiple types of resources, and it is difficult to realize dynamic matching and efficient cooperation between resources. The method comprises: obtaining operation data of the power distribution network; determining a photovoltaic predicted power based on historical photovoltaic output data; determining a storage charging and discharging reference value based on the photovoltaic predicted power and historical photovoltaic actual power; correcting the storage charging and discharging reference value based on the deviation between the photovoltaic real-time power and the photovoltaic predicted power, and the real-time demand of the power distribution network; the real-time demand of the power distribution network is determined based on the grid load degree and the surplus degree of photovoltaic power generation; and the transmission power of the converter and the scheduling of the flexible load are collaboratively controlled based on the corrected storage charging and discharging reference value and the deviation. The present application is used in the power grid control scene.
