【摘要】：隨著能源消耗與環(huán)境問題日益嚴(yán)重,電動汽車(PEV)作為低耗能、低污染的新型交通工具得到了大力發(fā)展,因此車電互聯(lián)技術(shù)(V2G)也被廣泛的研究和應(yīng)用。若能能合理地將電動汽車引入到電網(wǎng),并加以引導(dǎo)控制,不僅可以實(shí)現(xiàn)能源的充分利用,還能對電網(wǎng)的頻率和電壓等相關(guān)性能進(jìn)行調(diào)節(jié)。本文的研究目的旨在有序引導(dǎo)大規(guī)模電動汽車接入電網(wǎng)的充放電行為,并將其作為分布式電源向電網(wǎng)提供電壓頻率和幅值調(diào)節(jié)。本文提出一種價格更新機(jī)制作為V2G控制系統(tǒng)的算法來解決協(xié)同控制問題,此算法中電動汽車用戶能夠根據(jù)自己的成本函數(shù)和電池容量決定分配策略,電網(wǎng)通過所有的分配策略更新價格,系統(tǒng)迭代更新直到分配策略及價格不再更新,此時得到的策略最優(yōu)策略。本文對價格更新機(jī)制進(jìn)行了設(shè)計(jì),并證明了由此算法求得的分配策略為全局最優(yōu)策略,通過集中式控制和分布式控制兩種方式對V2G系統(tǒng)進(jìn)行仿真分析,顯示利用價格更新機(jī)制所求得策略為全局最優(yōu)策略。
[Abstract]:As energy consumption and environmental problems become more and more serious, electric vehicle (PEV), as a new type of vehicle with low energy consumption and low pollution, has been greatly developed. Therefore, vehicle power interconnection technology (V2G) has also been widely studied and applied. If the electric vehicle can be reasonably introduced into the power network and guided and controlled, it can not only realize the full utilization of energy, but also regulate the frequency and voltage of the power network. The purpose of this paper is to guide the charging and discharging behavior of large-scale electric vehicles (EVs) in an orderly manner and to provide voltage frequency and amplitude regulation to the grid as a distributed power source. In this paper, a price updating mechanism is proposed as an algorithm of V2G control system to solve the collaborative control problem. In this algorithm, electric vehicle users can decide the allocation strategy according to their own cost function and battery capacity. The power grid updates the price through all the allocation strategies, and the system iterates until the allocation strategy and the price are not updated, and the optimal strategy is obtained. In this paper, the mechanism of price updating is designed, and it is proved that the allocation strategy obtained by this algorithm is the global optimal strategy. The simulation analysis of V2G system is carried out by means of centralized control and distributed control. It shows that the strategy obtained by using the price update mechanism is the global optimal policy.
