Abstract
With the increasing prominence of energy crises and environmental issues, microgrids, as an essential carrier for the efficient utilization of distributed generation (DG), have become one of the key research areas in smart grids. This study focuses on the core issue of optimal DG allocation and coordinated control within microgrids, aiming to enhance the economic efficiency, reliability, and environmental sustainability of microgrid operations. Based on multi-ob jective optimization theory, a DG allocation method is proposed that comprehensively considers cost, emissions, and voltage stability, while a hierarchical control strategy is employed to achieve efficient coordination among various units within the microgrid. To address the complex nonlinear problems in optimal allocation, an improved particle swarm optimization algorithm is introduced, and a hybrid control fr amework combining droop control and power prediction is designed to accommodate demands under different operational modes. Simulation results demonstrate that the proposed approach can significantly reduce operational costs and pollutant emissions while effectively improving system voltage quality. Moreover, this research exhibits strong feasibility and versatility for practical engineering applications, providing critical references for the rational planning and efficient operation of distributed generation, and laying a theoretical foundation for the further development of microgrid technologies.
