大型城市电网负荷激增区域的源荷平衡方法研究
摘要:对于大型城市电网负荷激增区域的源荷平衡处理，往往采用协调调度的方式达到平衡的目的，但负荷变化的不确定性，严重影响了平衡方法的调度效果。针对这一情况，提出大型城市电网负荷激增区域的源荷平衡方法。依据负荷激增区域的负荷特性，以日前时间尺度和日内时间尺度作为分界线，搭建源荷实时调度框架，在此框架下制定源荷平衡的控制策略；并建立源荷平衡调度模型，对模型进行求解，得到的最优解即为最佳平衡方案。算例分析结果表明：提出的源荷平衡方法负荷调度效果好，能保证较高水平的能源利用率，整体适应性良好。
Abstract：Aim to achieve source-load balance for large cities where the power grid experiences significant load surges, coordinated scheduling is often employed. However, the uncertainty of load variations greatly impacts the effectiveness of such scheduling methods. In response to this situation, a method for achieving source-load balance in areas with significant load surges in large city power grids is proposed. Based on the load characteristics of these areas, a real-time scheduling framework for source-load balance is established, and the framework uses the division between the day-ahead time scale and the intra-day time scale as a reference point. Control strategies for source-load balance are developed within this framework, and a source-load balance scheduling model is established for solving, aiming to derive the optimal solution as the best balancing approach. Case study analysis results demonstrate that the proposed source-load balance method has a good load scheduling effect, ensuring a high level of energy utilization efficiency and exhibiting good overall adaptability.
