随着智能电网成为当前研究热点,作为其重要功能组成的分布式发电将在电力系统中得到越来越广泛的应用,分布式发电的优化配置问题变得尤为重要。文中针对分布式发电的优化配置问题进行了综述,对其国内外发展现状做了概括和分析。具体给出了几种常见的优化配置模型,重点介绍了建立在单目标优化基础上的分布式发电多目标综合优化配置模型;总结了分布式发电的优化配置方法,将其归类为解析方法、启发式方法和随机优化方法,还介绍了多目标函数的处理方法。最后探讨了组成微网的分布式发电的优化配置问题,并展望了分布式发电和微网优化的未来发展方向。
With the smart grid becoming the focus of current study, distributed generations (DGs) as one of the main functions in smart grid are increasingly widely applied in power systems, and the optimal allocation of DGs has become particularly crucial. A review is made of the optimal allocation of DG, with its current development at home and abroad summed up and analyzed. Some common optimization allocation models are given, especially those of comprehensive muiti-objective optimization based on single-objective optimization. Optimization allocation methods are boiled down to analytic methods, heuristic methods, and probability optimization methods plus those for multi-objective optimization. Finally, optimization allocation of DGs in the micro-grid is discussed, With the future development of DG and micro-grid optimization projected.
