Coordinated planning method for low-voltage power distribution network comprising electric heating equipment and photovoltaic power supply

Abstract

The embodiment of the invention provides a coordinated planning method for a low-voltage power distribution network containing electric heating equipment and a photovoltaic power supply. The method comprises the following steps: constructing a topological graph of the low-voltage power distribution network containing the electric heating equipment and the photovoltaic power supply; establishing a planning model, taking the highest comprehensive benefit of a user and a power supply enterprise as an optimization target, and providing operation constraints of the low-voltage power distribution network; and performing optimization calculation on the topological graph and the planning model by using a genetic algorithm, and determining the access position and the access capacity of the photovoltaic power supply. According to the method provided by the embodiment of the invention, negative effects on safe operation of a power grid and reduction of economic benefits of the photovoltaic power supply caused by the fact that the photovoltaic power supply is connected to the low-voltage power distribution network containing the electric heating equipment can be avoided, and comprehensive benefits of users and power supply enterprises are improved.
