Optimal Scheduling for Micro Energy Grid Considering Practical Network Constraints and Quality–quantity Regulation

The micro-energy grid with the adjustable mass flow can improve the economy and be more in line with engineering practice. In this paper, a multi-energy integrated micro-energy grid is proposed which contains PV, bedrock energy storage, electric refrigeration, solid oxide fuel cell, solar collector system, and energy storage. The structure of the heating network is considered in the optimal scheduling of the micro-energy grid, and quality–quantity regulation is used to accurately model the equipment in the heating network. In addition, a two-stage model of non-real-time heat exchange for the solar collector system is established. The results show that the proposed scheme has a better economy, environmental protection, and flexibility.
