Microgrid inverter grid disconnection/connection seamless switching control method based on phase angle estimation

, 2016
本发明涉及一种基于相角估算的微电网逆变器离并网无缝切换控制方法。使用储能系统作为主电源，包括储能电池、变流器、PCS模式控制器。在并网模式下使用PQ控制，孤岛模式下使用V/F控制。从并网至孤岛切换过程中电压幅值参考值由离网前电网相电压峰值给定，电压相角参考值由离网前电网角频率平均值和离网时刻的瞬时相角计算得到。从孤岛至并网切换过程中，利用基于电网电压瞬时值的相角估计算法更改逆变器V/F模式中相角参考值，快速跟踪电网相角，在PLL稳定锁相后，使用精准的电压相角代替估算值 ...

考虑用户偏好和阻塞管理的多微网分布式电能交易区块链模型

Gaoya dianqi
在多微网分布式电能交易市场中，用户偏好不完善、匹配机制不稳定会造成交易者违约，同时，潜在的线路阻塞问题也会影响配电网安全和交易效率。为此，提出考虑用户偏好和阻塞管理的多微网分布式电能交易区块链模型。首先，利用各微网主体申报价格、用户信誉值、历史合作基础、最大可供电能等信息构建用户合作偏好指标，并对购售电双方进行评估，形成合作偏好排序结果。其次，提出基于Gale-Shapley算法的双边匹配机制，使得参与主体能够在交易市场的双向选择中获得稳定匹配结果。再次，提出基于深度优先搜索（depth-first ...
