摘要
丽水用电负荷昼低夜高,呈现"峰谷倒置"现象,在现有水电上网峰谷电价机制下,有调节性能的电站普遍昼发夜停,不利于能源就地平衡。研究通过峰谷电价优化策略,发挥价格杠杆作用,实现"削峰填谷"。通过将传统的水电峰谷电价上网机制改为基准电价浮动机制,让有调节能力的水电在谷时段多发电,而在峰时段少发电。通过价格杠杆实现负荷"平滑"后,可以大大降低电网损耗,提高电能质量,大幅减少无功设备投切次数,提高电厂水资源利用率,具有极高的社会效益。
Power consumption load in Lishui is low at night and high by day, characterized by its peak-valley inversion. Under the present peak-valley feed-in tariff mechanism of hydropower, hydraulic power plants with regulation performance often operate at daytime and shut down at night, which goes against local balance.This paper investigates the optimization strategy of peak-valley price and takes advantage of price leverage to realize ＂peak shaving and valley filling＂. The transition from traditional peak-valley feed-in tariff mechanism of hydropower to standard price floating mechanism enables hydraulic power plants with regulation performance to generate more electricity in the valley time while generate less electricity in the peak time. The load smoothing through price leverage can greatly reduce grid loss, improve power quality, reduce switching times of reactive power equipment and improve water utilization power plant, which has very high social benefits.
