【摘要】：全面推廣節(jié)能環(huán)保的分布式發(fā)電能有效減少化石燃料的消耗，有利于解決當(dāng)前突出的環(huán)境問題、社會問題。但是，分布式發(fā)電的功率輸出具有波動性、隨機(jī)性、間歇性等特點(diǎn)，也給城市配電網(wǎng)帶來許多問題。城市配電網(wǎng)作為大電網(wǎng)的有機(jī)組成部分，直接關(guān)系到主動配電網(wǎng)和智能電網(wǎng)的發(fā)展安全性和可靠性，具有顯著的綜合經(jīng)濟(jì)效益。因此本文深入探究配電網(wǎng)規(guī)劃及分布式發(fā)電技術(shù)的發(fā)展前景，系統(tǒng)的分析了當(dāng)前的國內(nèi)外研究現(xiàn)狀。詳實(shí)、系統(tǒng)地研究光伏發(fā)電系統(tǒng)的原理，并且建立了光伏發(fā)電系統(tǒng)的物理模型和光伏逆變器的數(shù)學(xué)模型。針對城市配電網(wǎng)進(jìn)行了深入的研究，并且在技術(shù)層面上，深入分析光伏發(fā)電系統(tǒng)接入配電網(wǎng)的影響。針對光伏發(fā)電系統(tǒng)的選址、定容問題，采用有功、無功網(wǎng)損微增率來確定光伏發(fā)電系統(tǒng)的接入位置，提出綜合微增率，通過計算綜合微增率來確保城市配網(wǎng)系統(tǒng)的網(wǎng)損最小。同時提出了一種配電網(wǎng)接入光伏發(fā)電系統(tǒng)的多目標(biāo)規(guī)劃方法，充分考慮不可控光伏發(fā)電功率、負(fù)荷的不確定性，以配電網(wǎng)運(yùn)營商規(guī)劃期的經(jīng)濟(jì)成本、網(wǎng)損、環(huán)境和電壓質(zhì)量四方面的指標(biāo)為評價指標(biāo)構(gòu)成多目標(biāo)的函數(shù)，并采用混沌遺傳算法進(jìn)行求解，，并通過IEEE-30系統(tǒng)進(jìn)行仿真驗證，仿真結(jié)果表明采用該方法能夠?qū)崿F(xiàn)配網(wǎng)系統(tǒng)的合理優(yōu)化配置，從而保證城市配網(wǎng)系統(tǒng)的穩(wěn)定、可靠、安全運(yùn)行。
[Abstract]:The comprehensive promotion of distributed generation of energy saving and environmental protection can effectively reduce the consumption of fossil fuels and is conducive to solving the outstanding environmental and social problems at present. However, the power output of distributed generation has the characteristics of volatility, randomness and intermittency, which brings many problems to the urban distribution network. As an organic part of large power grid, urban distribution network is directly related to the development security and reliability of active distribution network and smart grid, and has significant comprehensive economic benefits. Therefore, this paper probes into the development prospect of distribution network planning and distributed generation technology, and systematically analyzes the current research situation at home and abroad. In detail, the principle of photovoltaic power generation system is studied systematically, and the physical model of photovoltaic power system and the mathematical model of photovoltaic inverter are established. Based on the research of urban distribution network, the influence of photovoltaic power system access to distribution network is analyzed in detail on the technical level. Aiming at the problem of location and constant capacity of photovoltaic power generation system, the access location of photovoltaic power generation system is determined by using active and reactive power loss increment rate, and the integrated micro-increment rate is put forward to ensure the minimum network loss of urban distribution network system by calculating the integrated micro-increment rate. At the same time, a multi-objective programming method for distribution network connected to photovoltaic generation system is proposed. The uncertainty of uncontrollable photovoltaic generation power and load is fully taken into account, and the economic cost and network loss of distribution network operators during the planning period are taken into account. The four indexes of environment and voltage quality constitute a multi-objective function, and are solved by chaos genetic algorithm, and verified by IEEE-30 system. The simulation results show that this method can realize the reasonable optimal configuration of the distribution network system, thus ensuring the stability, reliability and safety of the urban distribution network system.
