Research on power grid demand side management planning method considering distributed generation and interruptible load

Based on the distributed power grid connection and the energy planning of electric vehicles, this paper proposes a demand side management model using interruptible loads. According to the situation of the distribution network, it is proposed to use the comprehensive management cost as the planning objective function, comprehensively consider the parameters such as pipeline line loss, peak-valley level fluctuation, environmental resource benefits, etc., use MATLAB to simulate the model, take the IEEE-33 node model as the research object, and comprehensively consider the advantages and disadvantages of five distribution network planning schemes. The results show that the network system using interruptible loads and electric vehicles connected to the grid has the highest economic efficiency, and the economic benefits are about 22% lower than the original model. The system reliability is also more stable than other systems, which can be used to guide the planning of distribution networks.
