Abstract

Abstract: Multi-energy complementary micro-energy grid is an effective way to improve energy efficiency and reduce power supply costs through integrating multi-energy carriers.Against numerous energy converters of various types and storage devices with different characteristics, the selection of the type and capacity of the devices, and the connection and management of the selected devices are the key challenging problems for designing the optimal configurations of new micro energy grids. This paper proposes a new planning method of multi-energy complementary micro energy grid on user side, which can give full play to the advantages of multi-energy complementary and obtain the optimal configuration. The optimal planning model is a mixed-integer linear programming with the objective to minimize the overall cost. The effectiveness and superiority of the optimal planning model proposed in this paper are demonstrated by comparing three different energy system schemes with an energy interconnection demonstration project in Haidian District of Beijing.

Key words: micro energy grid, multi-energy complementary, structure planning, energy converter, renewable energy
