Abstract

Highlights: An economic dispatch model of Micro-grids is proposed. The operation characteristic and demand response of air-conditioner are considered. A distributed solution strategy is proposed. Abstract: An economic dispatch model of Micro-grids (MGs) considering flexible regulation demand response of central air-conditioning load is proposed in this paper. In the modeling of air-conditioning load interaction, the operation characteristics of air conditioning load and user's energy satisfaction requirements are considered in this paper. Moreover, to protect user's information privacy, a distributed solution strategy based on alternating direction method of multipliers with self-adaptive parameters (ADMM-SAP) is presented to achieve a distributed solution of MGs scheduling sub-problem and air-conditioning load scheduling sub-problem. Case studies demonstrate that the proposed model can achieve a better economic operation of MGs without violating central air-conditioning user's energy satisfaction, which can reduce total operation costs by 4.2%. And the ADMM-SAP based distribution solution strategy can achieve a distributed solution of two sub-problems without knowing the global information, which behaves a better convergence performance than standard ADMM.
