摘要：為應(yīng)對分布式能源波動性大、抗干擾能力較弱的問題，探索以分布式能源供電為主的獨(dú)立微網(wǎng)綜合資源配置意義重大。建立了含可中斷負(fù)荷的獨(dú)立微網(wǎng)綜合資源規(guī)劃優(yōu)化模型，將可中斷負(fù)荷的最大調(diào)用容量和分布式電源裝機(jī)容量同時(shí)進(jìn)行優(yōu)化規(guī)劃，以更好地發(fā)揮可中斷負(fù)荷在獨(dú)立微網(wǎng)中的作用，提高微網(wǎng)運(yùn)營經(jīng)濟(jì)性；應(yīng)用聚合機(jī)組模型等多種線性化建模方法將所建立的模型線性化，調(diào)用 CPLEX 求解器的混合整數(shù)線性規(guī)劃法對線性化后的模型進(jìn)行求解；通過仿真計(jì)算驗(yàn)證了所建立模型和采用方法的正確性，并從計(jì)算結(jié)果中得出可再生能源占比較高的獨(dú)立微網(wǎng)中可控電源和可中斷負(fù)荷的容量規(guī)劃策略。

關(guān)鍵詞： 獨(dú)立微網(wǎng)；分布式電源；可中斷負(fù)荷；容量優(yōu)化；混合整數(shù)優(yōu)化；聚合機(jī)組

Abstract: In order to cope with the problems of high volatility and weak anti-interference ability of distributed energy sources, it is significant to explore the integrated resource allocation of independent microgrids mainly powered by distributed energy sources. An integrated resource planning optimization model for independent microgrids containing interruptible loads is established, and the maximum calling capacity of interruptible loads and the installed capacity of distributed generation are optimized and planned at the same time, so as to better play the role of interruptible loads in independent microgrids and to improve the economics of microgrid operation; multiple linearization modeling methods, such as the aggregated unit model, are applied to linearize the established model, and the mixed-integer linear optimization method of the CPLEX solver is called to solve the linearized model. The correctness of the established model and the adopted methods are verified through simulation calculations, and the capacity planning strategies for controllable power sources and interruptible loads in independent microgrids with a high share of renewable energy are derived from the calculation results.

Key words: independent microgrid; distributed generation; interruptible load; capacity optimization; mixed-integer optimization; aggregated unit
