摘要
构建了风火储一体化电站,在假设燃煤机组达到无惯性延迟响应且储能电池可秒级切换充放电状态的极限情况下,规划适配该风火储一体化电站的优化调度策略;从电力波动率、弃电率和电力缺额率3个功率特性角度对风火储一体化电站与区域独立电站进行对比,并采用Matlab进行仿真验证。结果表明:相比区域独立电站,风火储一体化电站的电力波动率从1.306%降至0.178%,弃电率从0.667%降至0.145%,电力缺额率从0.643%降至0.010%,大幅提高了对AGC负荷指令的响应能力。
A wind-coal-battery coupling integrated power station was constructed,and the optimal scheduling strategy of the proposed power station was planned under the assumption that the coal-fired unit can reach no inertia delay response and the energy storage battery can switch the storage/release state in seconds.Besides,the proposed power station was compared with regional independent power station from the following aspects,such as power volatility rate,power abandonment rate and power shortage rate,which was verified by Matlab software.Results show that compared with regional independent power station,power volatility rate of the proposed power station decreases from 1.306% to 0.178%,power abandonment rate decreases from 0.667% to 0.145%,and power shortage rate decreases from 0.643% to 0.010%,indicating that the proposed power station greatly improves its response ability to automatic generation control(AGC) load command.
