建立了一种适用于网络化微电网的综合潮流算法。本文的新贡献包括：1)设计了一种适用于网络化微网的分布式增广潮流(APF)算法，以考虑微网内部和微网之间的分层控制效应；2)基于APF，建立了一种增强型分布式连续潮流算法(CPF$^+$)，用于探索静态电压稳定评估中的下垂系数和功率交换的运行区域；以及3)设计了一个可编程的分布式平台，以协调电力交换并支持即插即用，同时保护本地用户的隐私。RTDS实验验证了APF的高保真度，并在中、大型网络微电网上验证了其可扩展性和收敛性能。大量的测试证明了CPF$^+$在量化网络微电网安全运行区域方面的有效性。
An integrative power flow approach is established for networked microgrids. Our new contributions include: 1) A distributed augmented power flow (APF) algorithm for networked microgrids is devised to incorporate hierarchical control effects in/among microgrids; 2) Based upon APF, an enhanced distributed continuation power flow (CPF$^+$) algorithm is established to explore operating regions of droop coefficients and power interchanges for static voltage stability assessment; and 3) A programmable distributed platform is designed to coordinate power interchanges and support plug-and-play while protecting local customers’ privacy. RTDS experiments validate the high fidelity of APF, while its scalability and convergence performance are verified on medium and large networked microgrids. Extensive tests demonstrate the effectiveness of CPF$^+$ in quantifying secure operation regions of networked microgrids.
