Multi-energy microgrid robust energy management with a novel decision-making strategy

Abstract

Uncertainties in renewable energy sources and load demand have become a consequential issue which has led to a significant effect on the microgrid operation. In this paper, a novel cumulative relative regret decision-making strategy is proposed for the optimal energy management on a grid-connected multi-energy microgrid considering these uncertainties. The proposed strategy can ensure the robustness of the microgrid and reduce the conservatism of microgrid operation as compared with the traditional robust optimization method. Furthermore, the typical optimization model of microgrid energy management is improved by taking the demand response of the thermal load into account. The delay of heat transfer and the fuzziness of heating comfort are also investigated in order to obtain a more economic microgrid scheduling plan. Simulation results using different decision-making strategies are provided to verify the effectiveness of the proposed cumulative relative regret based robust optimization approach.
