Abstract

Highlights: In order to minimize the economic cost and carbon emissions, the optimization model of energy storage capacity is constructed. Micro energy system considering electric / thermal / gas coupling demand response. Adaptive dynamic weight factor is used to adapt to the flexible planning scene. Multi-objective optimization model of comprehensive planning of multiple energy storage forms. Abstract: Multiple energy storage devices in multi-energy microgrid are beneficial to smooth the fluctuation of renewable energy, improve the reliability of energy supply and energy economy. Taking the multi-energy microgrid with wind-solar power generation and electricity/heat/gas load as the research object, an energy storage optimization method of microgrid considering multi-energy coupling demand response (DR) is proposed in the paper. Firstly, the multi-objective optimization model of multiple energy storage capacity planning based on coupled DR was established with the objective of minimizing economic cost and carbon emission. Then, adaptive dynamic weighting factors are used to adapt to the flexibility of planning scenarios. At last, the economic performance and carbon emissions of the multi-energy microgrid before and after the application of coupled demand response are studied, and the configuration of energy storage system are compared with a numerical example to verify the proposed method effectiveness.
