Rolling Optimization of Economic Dispatching for Multi-energy Micro-grid System
摘要
Abstract
An optimal economic dispatching model of multi-energy micro-grid system within uncertain real-time sur?roundings is proposed in this paper. Given that the model involves random factors including renewable energy genera?tion,demand-side load and real-time price,a rolling optimization strategy is implemented to restrain their effects and maximize the energy utilization efficiency. Furthermore,considering the cogeneration of heat and power from the micro-grid system,a micro-turbine is regarded as the coupling unit,and the network power flow constraints are combined with the thermal balance constraints to establish an optimal power flow model of the multi-energy micro-grid. To comply with the mixed-integer and nonlinear features of the proposed model,an improved particle swarm optimization algorithm is applied with self-adaptive weight factor,and heuristic rules are used to confine the evolutionary direction of the thermal-power coupling units. The proposed model and its solution method are tested on a reconstructed IEEE 37-node distribu?tion system,and its effectiveness is validated by simulation results.关键词
