考虑合同能源管理的配网低碳优化及经济效益

Low-Carbon Optimization and Economic Benefit for Distribution Network Based on Energy Management Contract

中低压配电网是电力系统的重要组成部分,其损耗占整个电网损耗的50%左右,为此引入效益分享型合同能源管理机制,建立了配网节能低碳优化模型,采取了更换高效变压器、增加10 k V线路无功补偿、更换配网线路导线等低碳优化措施。结合某地区配电网运行现状实例计算,证明了基于合同能源管理的配电网低碳优化模式能有效地降低配电网损耗,提高电能质量和可靠性,且具有很好的节能效益,适于大范围的推广。

The Mid ＆ Low-voltage distribution network is an important part of power system, whose loss is around 50% of the power grid loss. Therefore, the benefit sharing energy management contract mechanism was introduced, and a distribution network optimization model for energy conservation and loss reduction was established. Energy saving optimization measures were replacing the high-efficiency transformer, adding 10 kV line reactive power compensation, changing the distribution network line wire, etc. In combination with the calculation of the present situation of a region distribution network operation, it is proved that the low-carbon optimization mode of distribution network based on energy management contract can reduce network loss effectively, improve power quality and reliability, and has good energy saving benefit, which is suitable for a wide range of promotion.
