Hierarchical energy management operation strategy considering hybrid demand response

Abstract

The invention relates to a hierarchical energy management operation strategy considering hybrid demand response. The hierarchical energy management operation strategy is technically characterized in that parameters are set and initialized; performing scene selection on the data set; analyzing an electric load in the user load layer; solving a multi-microgrid system layer; judging an optimal result and processing an abnormal value; if the internal transaction exists, an internal pricing strategy is executed, otherwise, a lower-layer result is transmitted to the active power distribution network layer; the active power distribution network energy decision center reads the information and feeds back the electricity selling condition to each micro-grid energy management system; judging whether the final result accords with expectation and processing; and judging whether a stop condition is met and outputting a result. According to the invention, a user load layer is introduced into each micro-grid system, a mixed demand response strategy is applied to layered energy management, and an electric load in a time period in which renewable energy sources are insufficient in output is reasonably transferred to a time period in which the renewable energy sources are excessive in output, so that the renewable energy sources are fully utilized, and the power supply pressure in a power utilization peak period is relieved.

Description

technical field [0001] The invention belongs to the technical field of layered energy management, in particular to a layered energy management operation strategy considering hybrid demand response. Background technique [0002] With the proposal of the "dual carbon" goal, my country's power industry will usher in a major opportunity for transformation and development. Renewable energy is connected to the active distribution network in the form of a multi-microgrid system, which plays an important role in alleviating the strong dependence on fossil energy. However, the randomness and volatility of renewable energy output will adversely affect the reliability of power system operation. Fully realizing the effective management of system energy in the active distribution network with multi-microgrid system is the key to ensure the safety, security and safety of the power system. The key to stability and economic functioning. In the multi-microgrid system, there are a large num...
