A power management strategy for balancing three single-phase sections in a three phase residential microgrids is presented in this paper. The scheme makes use of the previously developed intra- and inter-phase power management techniques to transfer power from the power surplus phase to power deficient ones to achieve dynamic phase balance. This scheme is particularly useful in situations where phase-dependent generation, single-phase loads, and home-based battery storage are involved, such as roof-top PVs, chargers for electric vehicles, and battery storage units. This scheme also opens up potential avenues for accommodating more advanced energy management programs among phases, such as peak shaving in different phases, and load shifting, to minimize potential risks of overloading substation transformers or forced load shedding due to power deficiency in one of the phases. Seven operating scenarios have been identified. Detailed power transfer models are developed and simulated in PSCAD/EMTDC to validate the proposed strategy. Experimental validation has also been carried out on a laboratory-scaled system involving a back-to-back converter.

住宅网络中具有分相发电和存储的三个单相部分的动态相位平衡

本文提出了一种平衡三相住宅微电网中三个单相部分的电力管理策略。该方案利用先前开发的相内和相间功率管理技术，将功率从功率过剩相转移到功率不足相，以实现动态相位平衡。该方案在涉及相依赖发电、单相负载和家庭电池存储的情况下特别有用，例如屋顶光伏、电动汽车充电器和电池存储单元。该方案还开辟了在各相之间采用更先进的能源管理方案的潜在途径，例如不同相的调峰和负荷转移，以最大限度地减少由于其中一相电力不足而导致变电站变压器过载或强制减载的潜在风险。已经确定了七种操作方案。在 PSCAD/EMTDC 中开发并模拟了详细的功率传输模型，以验证所提出的策略。还在涉及背靠背转换器的实验室规模系统上进行了实验验证。
