发布时间：2019-04-24 13:33
【摘要】：电池储能系统(BESS)可使风电场具备一定的发电计划跟踪能力,有必要研究风电场中的BESS容量优化问题。根据BESS技术特性与风功率波动特性制定发电计划,BESS分两部分运行,分别处于充、放电状态,交替平抑风功率与发电计划间的正、负偏差。一旦任一部分BESS到达满充或满放状态,则同时切换两部分BESS的工作状态。采用蒙特卡洛模拟技术对风-储混合电站一年内的运行状况进行模拟,并计算发电计划跟踪概率与BESS运行利润。在确保风-储混合电站按期望置信度跟踪发电计划的基础上,依据利润最大化的原则对BESS容量进行优化。基于某风电场历史数据的仿真实验证明了所提模型及算法的有效性。
[Abstract]:The battery energy storage system (BESS) can make the wind farm have the ability to track the power generation plan. It is necessary to study the optimization of BESS capacity in the wind farm. According to the technical characteristics of BESS and the characteristics of wind power fluctuation, the power generation plan is made. The BESS is operated in two parts, which are in charge and discharge states respectively. The positive and negative deviations between the alternately balanced wind power and the generation plan are determined. Once any part of the BESS reaches the full charge or full discharge state, it switches the working state of both parts of the BESS at the same time. Monte Carlo simulation technique is used to simulate the operation of the wind-storage hybrid power station within one year, and the tracking probability of the power generation plan and the operation profit of the BESS are calculated. According to the principle of profit maximization, the capacity of BESS is optimized on the basis of keeping track of the scheduled reliability of the wind-storage hybrid power station. Simulation experiments based on historical data of a wind farm demonstrate the effectiveness of the proposed model and algorithm.
