Abstract
Smart grids, as a critical direction in the development of modern power systems, rely on efficient power dispatching for stable operation. To address the inadequacies of traditional dispatching methods in handling complex grid structures and fluctuating load demands, this study focuses on exploring optimization algorithms for power dispatching in smart grids. Aiming to enhance the operational efficiency, reduce operational costs, and improve stability of power systems, an improved particle swarm optimization (PSO) algorithm-based dispatching strategy is introduced. By integrating multiple heuristic rules, this algorithm ensures global search capability while improving local search precision, effectively addressing issues of slow convergence and susceptibility to local optima in high-dimensional complex problems. Experimental results demonstrate that the proposed algorithm can rapidly and accurately solve large-scale power system dispatching problems, reducing average computation time by approximately 30% and increasing the cost-effectiveness of dispatching solutions by over 25% compared to traditional methods. Furthermore, to account for uncertainties introduced by renewable energy integration, a stochastic scenario model incorporating wind and photovoltaic power sources is constructed, and scenario reduction techniques are employed to simplify the solution process, ensuring robust dispatching decisions. This research not only provides an effective solution for power dispatching in smart grid environments but also promotes the accommodation of clean energy and advances the construction of the energy internet, laying a theoretical foundation and offering practical references for future studies in related fields.
