摘要
针对以往风电场并网采用蓄电池储能装置平滑风能波动研究中的不足,提出了在实现SOC控制前提下,考虑满足平抑指标要求的充放电控制步长和电池使用寿命的电池容量配比优化算法。结合沿海风电场的实际输出功率数据进行了仿真验证,并讨论了所需电池的充放电倍率与容量的关系,分析了储能的能量损耗,为风储联合发电的示范工程提供理论依据和参考。仿真结果表明,配置方案具有较强可行性和有效性。
The fluctuation of wind power has many adverse effects on its grid integration, which can be suppressed by using battery energy storage device commonly. For overcoming the shortage of comprehensive studies about the issue, an optimization algorithm of battery capacity configuration was proposed which considers battery life time and control step length of battery charging and discharging under the condition of meeting the attenuation requirements of wind power fluctuation with battery SOC control. Simulation was conducted under the actual wind farm historical data of an island and the relationship between charge-discharge rate and the required battery capacity was discusse8d. The energy loss of energy storage was also analyzed. This paper provided a theoretical basis and reference for the demonstration project of combined power generation between wind and energy storage system （ESS）. The results based on real wind farm historical statistics show the feasibility and effectiveness of the proposed capacity configuration and control algorithm.
