Gaoya dianqi, 2021 优化调度策略是有源配电网对分布式能源实施主动管理的核心技术,也是有源配电网安全经济运行的重要保障。文中以不同类型分布式电源的出力为控制变量,构建了突出电压质量提升和运行成本降低为目标的模糊化调度模型。引入均匀分布的初始和声库及变维数和声记忆库对基本和声搜索算法的改进用于调度模型的求解。通过IEEE33节点系统上的大量仿真测试和比较分析,验证了所建立的优化调度模型和改进算法的正确性和有效性。

Dianci bileiqi, 2011 通过调研湖南、广西、河南等省的农网10kV配电变压器的运行情况,结合分析其配电变压器在防雷保护方面的现状,指出了目前的问题主要存在于接地装置和低压侧避雷器装设等方面,用理论计算和仿真分析的方法对存在的问题进行了研究,认为严格限制配变台区接地装置的接地电阻,并做好防腐处理;配电变压器高、低压侧装设避雷器保护;加强对雷电活动强烈的配变台区的巡视检查是切实有效、可行的方案,建议供电部门实施。
