本文主要研究微电网的能量不平衡管理问题。本文从电力市场的角度来研究这一问题。与传统电网不同，微电网可以从太阳能电池板或风力涡轮机等可再生能源（RES）中获得额外的能量。然而，可再生能源的随机输入给能源供需平衡带来了困难。在这项研究中，提出了一种新的定价方案，以提供对这种间歇性电力输入的鲁棒性。该方案考虑了电力市场边际效益和边际成本可能存在的不确定性。它使用了所有关于电力供应、电力需求和不平衡能源的可用信息。该方案的参数使用性能指标进行评估。结果表明，该参数可通过求解线性矩阵不等式问题得到，该问题由于其凸性而可有效求解。仿真结果表明，该方案与现有的区域控制误差定价方案相比具有良好的性能。线性矩阵不等式问题，区域控制误差定价方案。
This paper focuses on the problem of energy imbalance management in a microgrid. The problem is investigated from the power market perspective. Unlike the traditional power grid, a microgrid can obtain extra energy from a renewable energy source (RES) such as a solar panel or a wind turbine. However, the stochastic input from the RES brings difficulty in balancing the energy supply and demand. In this study, a novel pricing scheme is proposed that provides robustness against such intermittent power input. The proposed scheme considers possible uncertainty in the marginal benefit and the marginal cost of the power market. It uses all available information on the power supply, power demand, and imbalanced energy. The parameters of the scheme are evaluated using an performance index. It is shown that the parameters can be obtained by solving a linear matrix inequality problem, which is efficiently solvable due to its convexity. Simulation examples are given to show the favorable performance of the proposed scheme in comparison with existing area control error pricing schemes.linear matrix inequality problem,area control error pricing schemes.
