Abstract: With the increase of electric vehicle penetration, the coupling of power network and transportation network in time and space is closer. In order to reduce the challenges brought by the disorderly integration of electric vehicles to the safe and stable operation of power system, this paper fully considers the influence of power load demand and traffic condition uncertainty, and establishes a multi-agent interest hierarchical game model of EV users-charging station aggregators-grid operators. On the premise of satisfying the constraints, the multi-agent interest hierarchical optimization problem is solved based on improved bat algorithm. The simulation example shows that the grid operators can obtain higher operating benefits by actively adjusting the pricing strategy for different electric vehicle penetration rates. The proposed method can effectively improve the voltage quality of power grid to ensure the safe and stable operation of the system, and provide theoretical support for improving the value chain system of power industry.
Key words : power-traffic coupling network;multi-agent interests,;locational marginal price,;improved bat algorithm;optimal pricing

在實(shí)現(xiàn)碳達(dá)峰,、碳中和的目標(biāo)指引下,,電動(dòng)汽車(Electric Vehicles, EV)作為一種綠色清潔的出行工具,對(duì)減小溫室氣體排放和降低環(huán)境污染發(fā)揮著積極作用[1-2],。若EV未經(jīng)管理無(wú)序并入電網(wǎng),,會(huì)對(duì)電網(wǎng)的安全穩(wěn)定運(yùn)行造成較大的沖擊[3-4]。因此,,通過(guò)建立EV并網(wǎng)的電力-交通耦合驅(qū)動(dòng)充電模型,,充分利用EV時(shí)空靈活性,實(shí)現(xiàn)多方利益最大化[5-6],。

針對(duì)電力-交通耦合驅(qū)動(dòng)充電模型,,國(guó)內(nèi)外專家學(xué)者對(duì)此已展開(kāi)相關(guān)研究。文獻(xiàn)[7]以最小化EV用戶出行成本和電網(wǎng)運(yùn)行成本為目標(biāo),,通過(guò)迭代列生成算法求解計(jì)算,,實(shí)現(xiàn)電網(wǎng)運(yùn)營(yíng)商調(diào)控EV用戶的行駛路徑和充電位置優(yōu)化。文獻(xiàn)[8]綜合考慮電力系統(tǒng)和交通系統(tǒng)交互影響,,提出一種用于引導(dǎo)EV充放電行為的分層博弈方法,,所提方法能提高配電網(wǎng)運(yùn)行可靠性和充電樁的經(jīng)濟(jì)效益。文獻(xiàn)[9]針對(duì)不確定性風(fēng)險(xiǎn)給電網(wǎng)運(yùn)行帶來(lái)的挑戰(zhàn)提出一種電力-交通耦合的網(wǎng)絡(luò)最優(yōu)定價(jià)方法,,該策略能夠有效優(yōu)化系統(tǒng)的整體運(yùn)行性能,。文獻(xiàn)[10]同時(shí)考慮電力網(wǎng)和交通網(wǎng)的時(shí)序特性,提出一種含高比例EV的電力交通耦合網(wǎng)絡(luò)建模方法,,所提方法能夠提高電力-交通耦合網(wǎng)絡(luò)的魯棒性和安全性。上述文獻(xiàn)針對(duì)電力網(wǎng)絡(luò)和交通網(wǎng)絡(luò)的時(shí)空耦合性進(jìn)行相應(yīng)研究,,但未充分考慮EV滲透率不同對(duì)電網(wǎng)運(yùn)行帶來(lái)的影響,。

本文以電網(wǎng)運(yùn)營(yíng)商的角度出發(fā),考慮電力負(fù)荷需求和交通路況不確定性對(duì)電網(wǎng)運(yùn)行的影響建立電力-交通耦合優(yōu)化模型,,針對(duì)所提多主體利益分層博弈模型制定最優(yōu)定價(jià)策略,。首先,,建立EV用戶-充電站聚合商-電網(wǎng)運(yùn)營(yíng)商多主體利益分層博弈模型,推導(dǎo)各主體運(yùn)行目標(biāo),。其次,,基于改進(jìn)型蝙蝠算法對(duì)所提多主體利益分層優(yōu)化問(wèn)題求解得到最優(yōu)運(yùn)行策略。最后,,通過(guò)仿真算例驗(yàn)證本文所建立模型能有效提高系統(tǒng)運(yùn)行的經(jīng)濟(jì)效益和促進(jìn)電網(wǎng)的安全穩(wěn)定運(yùn)行,。
