Research on optimal configuration of park-level multi-energy complementary system with multiple evaluation indexes

Abstract

At present, the shortage of energy is becoming more and more serious, and the ecological environment is deteriorating. The proposal of the concept of park level multi energy complementary system (MECS) provides direction for achieving environmentally friendly and sustainable energy development. In recent years, how to set the capacity and scheduling methods of equipment to improve the economy and reliability of the system has become a hot research topic in this field. In this paper, a two-layer optimal scheduling strategy is proposed to allocate the capacity of various energy equipment in the park, considering the comprehensive energy self-sufficiency rate, comprehensive energy utilization rate and energy shortage expectation. The proposed capacity allocation scheme can effectively improve the economy of MECS in the park. Finally, the effectiveness and practicability of the algorithm are verified by simulation analysis.
