Household multi-microgrid system optimization control method based on event-driven automatic demand response

Abstract

The invention discloses a household multi-microgrid system optimization control method based on event-driven automatic demand response. The method comprises the steps of: building a multi-microgrid system model according to the power supply and consumption information of a supply side and a demand side of a household multi-microgrid system; analyzing the operation condition of the household multi-microgrid system, determining an event type and a triggering condition, and establishing an event triggering mechanism; establishing a household resource scheduling model for the event type in the microgrid, and guiding a network access load to complete self power consumption optimization by taking the lowest daily operation cost of the household microgrid as a target and combining the real-time electricity price and the scheduling potential; and establishing an energy sharing model for power interaction between microgrids, calculating the energy level of each sub microgrid in the system withthe purpose of maximizing the overall interaction benefit of the system, and deciding the interaction power between the microgrids according to the historical participation degree and related scheduling criteria of the sub microgrids. According to the invention, the operation cost of the household multi-microgrid system is effectively reduced, the renewable energy consumption rate of the system isimproved, and the automatic demand response of the system is achieved.

Description

technical field [0001] The invention relates to an event-driven automatic demand response-based optimization control method for a household multi-microgrid system. Background technique [0002] In the face of increasingly severe energy and environmental problems, it is no longer a long-term solution to rely solely on fossil energy to supply human daily work. Therefore, the development of renewable energy has become the current mainstream direction in the energy field of countries around the world. Among them, the Energy Internet combining information technology and renewable energy is the current mainstream research direction. However, the span from microgrid to Energy Internet is too large to be realized. Therefore, some scholars have proposed the concept of interconnected microgrids. The interconnected microgrids are also called multi-microgrid systems, which can interconnect multiple microgrids close to each other and coordinate management of multiple microgrids in the en...
