Research on Optimal Operation Strategy of Distributed Energy Based on Distribution Network Planning

Abstract

Distributed energy is an energy supply mode based on load demand side. It aims at maximizing energy utilization and environmental benefits, integrates and optimizes various energy demands and resource allocation of users, and adopts a new energy system with demand response design and modular allocation. Because most of the energy it consumes is renewable and clean, it is environmentally friendly. Energy community is an important part of active distribution system. The method of power grid planning is studied and analyzed, and the energy management model of energy community is established. On this basis, the active distribution system is studied comprehensively and solidly. The research results can effectively improve the economy and reliability of active distribution system, and promote the large-scale grid connection of renewable energy. By using the heat storage system to periodically transfer heat load, the contradiction between the ratio of electric load to heat load in microgrid and the electric heat ratio of cogeneration system can be alleviated, thus realizing efficient and economical electric heat dispatching.
