摘要
提出一种含有电力弹簧的微电网能量优化模型。考虑电力弹簧作为微电网负荷调节的一种媒介,根据非关键负荷特性建立智能负荷的调节模型。根据风电出力和多种负荷预测曲线,对该能量优化模型进行分析计算;定量分析电力弹簧在计及储能充放电成本、弃风成本、电力弹簧设备折旧成本和负荷调节补贴的微电网能量优化中的作用。算例和仿真结果验证了所提能量优化模型的正确性和有效性。
An energy optimization model of microgrid with ES(Electric Spring) is proposed. Since ES is a medium for load regulation of microgrid,a regulation model of smart load is established based on non-critical load characteristics. According to wind power output and various load forecasting curves,the energy optimization model is analyzed and calculated,and the role of ES in energy optimization of microgrid is quantitatively analyzed with the consideration of charging and discharging cost of energy storage,abandoned wind cost,depreciation cost of ES equipment and load regulation subsidy. Case and simulative results verify the correctness and effectiveness of the proposed model.
