A Method for Energy Supply Unit Partitioning in Multi-Energy Distribution System Considering Flexible Adjustment Capability of Demand Response

In order to achieve the goal of “carbon neutrality and carbon peak”, the new distribution system with multi-energy complementary and integration has become an important development direction and construction path of future distribution network. In order to adapt to the actual situation of multi-type power equipment access and multi-energy integrated supply, it is necessary to carry out the research on the planning method of energy supply unit centered on electricity. Aiming at the new distribution system with flexible access of multi-type load and distributed generation, this paper considers the uncertainty of different types of load and distributed generation, and proposes an uncertainty handling method based on three-point estimation and Gram-Charlier expansion. Considering the differentiated demand response regulation capability of different types of loads, an energy supply unit optimization partitioning method satisfying the feeders N-1 criterion is proposed. By setting the actual regions to be planned as an example and considering the results of energy supply unit partitioning under different demand response adjustment capabilities, the economy, safety, and effectiveness of the proposed method are verified.
