In order to master the aggregated load characteristics of the grid-connected microgrid to serve the planning and operation of the distribution network, the operation strategies and aggregated load characteristics of the grid-connected microgrid under the differential power price are studied. This paper investigates the market mechanism of domestic and foreign microgrids and establishes power configuration modes for different types of microgrids. Under the current differentiated distributed power tariff, considering various power tariffs and generation costs, the output strategies and state change paths for different power scenarios are proposed. Based on this, a solution method based on adaptive immune particle swarm algorithm is presented. Through a large number of simulations, the aggregated load characteristics of the grid-connected microgrid are extracted, which provides a reference for the planning, operation and price mechanism of the microgrid and distribution network.
