摘要： 随着农村清洁供热改造以及城镇分布式光伏建设的不断推进，配电网中出现了大量农村微电网。分布式光伏的强随机性和波动性给电网的运行调控带来了诸多挑战，电网面临剧烈的潮流波动和严重的电压越限等问题。首先，构建了计及热泵、光伏和储能的配微网分解协调模型，其中热泵用等效状态空间模型描述；然后，提出一种配微网有功无功协调优化方法，并采用改进的Benders分解算法进行求解；最后，在D141-M4算例系统上进行了算例测试。测试结果表明，所提方法可以在保证用户舒适度的前提下，有效降低电网峰值负荷，并提升电压安全水平。

Abstract: With the progress of the transformation of rural clean heating and the construction of urban distributed photovoltaics, a large number of rural microgrids have appeared in the distribution networks. However, the strong randomness and volatility of distributed photovoltaics also bring many challenges to the operation of the power systems and make the power grids face such problems as severe power flow fluctuations and voltage violations. Firstly, a decomposition and coordination model is constructed for distribution networks and microgrids considering heat pumps, photovoltaics and energy storage systems , in which the heat pumps are described by the equivalent state space model. Subsequently, an improved Benders decomposition algorithm is proposed to solve the active and reactive power coordination problem of distribution networks and microgrids. Finally, numerical tests are carried out on the D141-M4 system, which has verified the validity of the proposed method in reducing the peak load and alleviating voltage violations on the premise of ensuring the users' comfort.

Key words: coordinated optimization of distribution networks and microgrids, rural microgrid, heat pump, distributed photovoltaic, voltage optimization, Benders decomposition
