摘要
为解决电网高峰时期供电不足的问题,提出了一种考虑分布式电源接入的主动配电网降压节能方法,旨在实现主动配电网降压运行,并在满足供电电能质量要求的前提下实现最低总能耗.首先通过增加有载调压变压器(OLTC)和分组投切电容器(CB)等调节设备,实现主动配电网降压运行,然后采用ZIP负荷模型进行优化,最后通过某城区 10kV配电网算例分析,验证了所提方法的可行性.研究结果表明,该方法在满足供电电能质量要求的同时,能够减少总能耗,降低用能成本,提高电网运行的经济性.
Abstract
To solve the problem of insufficient power supply during peak periods of the power grid,a conservation voltage reductio method using active distribution networks considering the integration of distributed power sources is proposed in this study,aiming at voltage-reduced operation of active distribution networks,and minimization of total energy consumption with power supply maintained standard-qualified.First by adding on-load tap-changing transformers(OLTC)and capacitor bank switching(CB)and other regulating devices,the voltage-reduced operation of active distribution network is achieved.Then the ZIP load model is used for optimization.Finally an analysis on a 10 kV distribution network in a certain urban area is carried out for feasibility verification.The proposed method is confirmed by sufficient results capable of reducing total energy consumption and energy costs and improving the economy of power grid operation,while meeting the requirements of power supply quality.
