基于虚拟电池模型的低压台区多时间尺度优化调度策略
Multi-time Scale Optimal Scheduling Strategy for Low-voltage Area Based on Virtual Battery Model
摘要
Abstract
In recent years,China has actively promoted the high-quality development of distributed energy.However,the uncertainty of distributed energy output has led to insufficient flexibility of the power system,causing the power grid to face dual challenges:inadequate peak regulation and energy consumption capacity.To address these issues,a day-ahead and intraday multi-time scale optimal dispatching strategy based on a virtual battery model is proposed.Firstly,a virtual battery model is established to quantify and integrate distributed flexible resource clusters.Then,the Minkowski sum is used to calculate the feasible region of flexible resources,which serves as a constraint linking the day-ahead and intraday dispatching models.To improve the reliability of the intraday optimization results,a distributed consistency algorithm based on gradient descent is adopted for solving the problem.Finally,a case study of an actual transformer area is conducted.By comparing it with the traditional model,the superiority of the proposed model is verified.Simulation results show that the virtual battery model can enhance the operational flexibility of the transformer area,improve economic benefits,and increase the photovoltaic utilization rate.关键词
