【摘要】：高渗透率的不可控分布式电源的接入引起配电网安全运行问题日益显著,无功电源能够有效缓解配电网的运行风险。基于此,文中在无功电源规划阶段充分考虑光伏和负荷的时序特性,建立以马尔科夫链为基础的时序模拟模型,并构建了考虑主动配电网调压需求的时序综合灵敏度选址方法,然后计及配电网的主动管理形成了投资层面和模拟运行层面的无功电源二层规划模型,投资层考虑转换为等年值的静止同步补偿器(static synchronous compensator,STATCOM)的投资成本,运行层考虑配电网的年运行费用,并采用遗传算法进行求解,算例结果表明:所提方法充分考虑了主动配电网的多种特点,有效降低了配电网损耗、改善配电网电压水平。
[Abstract]:The access of uncontrollable distributed generation with high permeability causes the problem of safe operation of distribution network becomes more and more significant. Reactive power supply can effectively alleviate the operational risk of distribution network.Based on this, the timing characteristics of PV and load are fully considered in the reactive power planning stage, and the time series simulation model based on Markov chain is established, and the time series comprehensive sensitivity location method considering the demand of voltage regulation in active distribution network is constructed.Then, considering the active management of the distribution network, the two-layer reactive power source planning model is formed at the investment level and the simulated operation level, and the investment level considers the investment cost of the static synchronous compensator (STATCOMV) converted to the equal annual value of the static synchronous compensator.The operation layer considers the annual operation cost of the distribution network and solves it by genetic algorithm. The results show that the proposed method fully takes into account the various characteristics of the active distribution network, effectively reduces the loss of the distribution network and improves the voltage level of the distribution network.
