【摘要】：近年來(lái)能源和環(huán)境問(wèn)題不斷惡化，致使分布式發(fā)電技術(shù)備受關(guān)注。分布式發(fā)電在綜合效率、能源多樣化、環(huán)保、節(jié)能、資源節(jié)約、供電可靠性等方面都具有顯著的優(yōu)越性。然而，分布式發(fā)電大規(guī)模并網(wǎng)運(yùn)行容易引發(fā)安全穩(wěn)定和能源管理等一系列系統(tǒng)性問(wèn)題。為了有效解決分布式電源大規(guī)模并網(wǎng)狀態(tài)下所引發(fā)的諸多問(wèn)題，充分發(fā)揮其潛能，，在分布式發(fā)電技術(shù)領(lǐng)域產(chǎn)生了微電網(wǎng)的概念。微電網(wǎng)(Microgrid, MG)是由分布式電源、儲(chǔ)能裝置、能量變換裝置、相關(guān)負(fù)荷、監(jiān)控裝置和保護(hù)裝置匯集而成的小型發(fā)配電系統(tǒng)。微電網(wǎng)既可以作為單一可控單元與大電網(wǎng)友好并網(wǎng)，也能夠從主網(wǎng)脫離出來(lái)成為可控自治系統(tǒng)。無(wú)論哪種工作模式，微電網(wǎng)都需作為可定制電源為所轄重要負(fù)荷提供可靠的多種能源形式供應(yīng)。由于微電網(wǎng)中微電源行為特性和供電形式多樣，致使其能源管理問(wèn)題非常復(fù)雜。 本文從微電網(wǎng)的經(jīng)濟(jì)效益和環(huán)境效益角度出發(fā)，分別建立能量?jī)?yōu)化的目標(biāo)函數(shù)，并在考慮微電源特性以及傳輸線路的約束的情況下，用多目標(biāo)處理方法將目標(biāo)函數(shù)轉(zhuǎn)換為單目標(biāo)函數(shù)進(jìn)行求解；考慮微電網(wǎng)的市場(chǎng)環(huán)境，引入電力市場(chǎng)下微電網(wǎng)與大電網(wǎng)之間的實(shí)時(shí)電力交易，針對(duì)微電網(wǎng)在電力市場(chǎng)的交易競(jìng)價(jià)，建立了一種多代理系統(tǒng)控制下的優(yōu)化模型；討論了一種博弈競(jìng)價(jià)的方法及其在電力市場(chǎng)中的應(yīng)用，并將優(yōu)化電價(jià)運(yùn)用到微電網(wǎng)能量?jī)?yōu)化的模型中；最后用一種改進(jìn)的粒子群算法迭代出最優(yōu)結(jié)果，并用算例的仿真檢驗(yàn)優(yōu)化結(jié)果的正確性。
[Abstract]:In recent years, energy and environmental problems have been worsening, which has caused much attention to distributed power generation technology. Distributed power generation in comprehensive efficiency, energy diversification, environmental protection, energy conservation, resource conservation, Power supply reliability and other aspects have significant advantages. However, In order to solve the problems caused by large-scale grid connection of distributed generation, it is easy to cause a series of systemic problems, such as security and stability, energy management, etc. In order to effectively solve many problems caused by large-scale grid connection of distributed power supply, the potential of distributed power generation can be brought into full play. The concept of microgrid is developed in the field of distributed generation technology. Microgrid (MG) is composed of distributed generation, energy storage device, energy conversion device, related load. A small power generation and distribution system composed of monitoring and protection devices. Microgrid can be used as a single controllable unit and a large power grid to be connected to the grid, or can be separated from the main network into a controllable autonomous system. Microgrid should be used as a customizable power source to provide reliable energy supply for important loads under its jurisdiction. Due to the diversity of behavior characteristics and power supply forms of micro-power supply in micro-grid, the energy management problem is very complex. From the point of view of economic and environmental benefits of microgrid, the objective function of energy optimization is established, and the characteristics of micro-power supply and the constraints of transmission line are considered. The multi-objective processing method is used to solve the problem by converting the objective function into a single-objective function, considering the market environment of microgrid, introducing the real-time electricity transaction between microgrid and large power grid under the power market, and aiming at the transaction bidding of micro-grid in the power market. An optimization model under the control of multi-agent system is established, and a game bidding method and its application in power market are discussed, and the optimized electricity price is applied to the model of micro-grid energy optimization. Finally, an improved particle swarm optimization algorithm is used to iterate out the optimal results, and an example is used to verify the correctness of the optimal results.
