【摘要】：隨著我國電力需求的持續(xù)增長,一些經(jīng)濟發(fā)達省市夏季高峰負荷不斷升高,解決電力供應(yīng)不平衡問題僅依賴發(fā)電側(cè)資源調(diào)節(jié)是不經(jīng)濟,不安全的。如果利用需求響應(yīng)措施則可以更好地引導(dǎo)用戶,調(diào)動需求側(cè)資源例如電動汽車、大規(guī)�？照{(diào)及蓄熱蓄冰設(shè)備等與電網(wǎng)互動,緩解資源與環(huán)境的壓力。電價機制作為需求響應(yīng)的重要組成部分,可以利用價格杠桿起到削峰填谷的作用,其扮演的角色也將越來越重要�，F(xiàn)階段我國普遍實行的是分時電價,但是分時電價是費率相對固定的靜態(tài)電價,已試點的尖峰電價實質(zhì)也為尖-峰-平-谷分時電價,動態(tài)性較差。因此,設(shè)計合理的動態(tài)尖峰電價機制有針對性地引導(dǎo)用戶減少或者轉(zhuǎn)移尖峰負荷有著重要的理論和實際意義。本文在借鑒國內(nèi)外經(jīng)驗的基礎(chǔ)上,提出了一種考慮用戶響應(yīng)的動態(tài)尖峰電價優(yōu)化決策模型。在所提出的尖峰電價中,首先給出了利用閾值和模糊隸屬度動態(tài)確定尖峰日和尖峰時段的方法,接著基于用戶對尖峰電價的響應(yīng),建立了尖峰電價優(yōu)化決策模型,兼顧了電網(wǎng)公司和用戶的利益,并綜合考慮了用戶滿意度、月平均電價不變和防止“尖峰漂移”等問題。仿真結(jié)果表明尖峰電價能明顯起到減少尖峰負荷,改善負荷特性的效果,同時也能減少用戶的電費支出。其次,本文探討了所提尖峰電價對于電動汽車這種重要需求側(cè)資源的影響。在本文的研究中,根據(jù)相關(guān)數(shù)據(jù)統(tǒng)計利用蒙特卡洛方法對無序隨機充電模式、有序充電模式和V2G模式等三種充電情景的充放電負荷曲線進行模擬,分析尖峰電價優(yōu)化前后的變化。通過仿真可知,尖峰電價可以明顯改善電動汽車充放電負荷“峰上加峰”的問題,同時電動汽車與電網(wǎng)的雙向互動也可進一步提高電網(wǎng)可靠性。最后,為了更好地促進尖峰電價的推廣實施,建立了相關(guān)的評價體系。在本文的綜合評價體系中,對尖峰電價實施效果進行了梳理,建立了合適的框架,并定義了評價指標,采用模糊層次分析法進行評價。此評價機制可以提供恰當?shù)姆答佇畔?給電力公司、用戶及政府相關(guān)部門提出有效的配套意見,對進一步完善尖峰電價機制有著重要意義。
[Abstract]:With the continuous growth of power demand in China, the peak load of some economically developed provinces and cities is increasing in summer. It is not economical to solve the problem of power supply imbalance only relying on generation side resource regulation. Unsafe. If you use demand response measures, you can better guide users, mobilize demand-side resources such as electric vehicles, large-scale air conditioning and ice storage equipment to interact with the grid. As an important part of demand response, electricity price mechanism can use price lever to cut the peak and fill the valley. Its role will also be more and more important. At this stage, China generally implements the time-sharing price, but the time-sharing price is the static price with relatively fixed rate. The peak-peak price is also peak-peak-equal-valley time-sharing price, which is less dynamic. It is of great theoretical and practical significance to design a reasonable dynamic peak-price mechanism to guide customers to reduce or transfer peak load. In this paper, a dynamic peak-price optimization decision model considering user response is proposed. In the proposed peak-price, the method of dynamically determining peak day and peak time by using threshold and fuzzy membership degree is given. Then, based on the response of customers to peak price, a decision model of peak price optimization is established, which takes into account the interests of power grid companies and users, and comprehensive consideration of customer satisfaction. The simulation results show that the peak price can obviously reduce the peak load, improve the load characteristics, but also reduce the user's electricity expenditure. Secondly, the simulation results show that the peak price can obviously reduce the peak load and improve the load characteristics. In this paper, the effect of peak price on the demand side resource of electric vehicle is discussed. In this paper, the random charging mode is analyzed by Monte Carlo method according to the relevant data. The charge and discharge load curves of three charging scenarios, such as orderly charging mode and V2G mode, were simulated to analyze the changes of peak price before and after optimization. The peak price can obviously improve the charge and discharge load of electric vehicle. At the same time, the two-way interaction between electric vehicle and power grid can also further improve the reliability of power grid. In order to promote the promotion and implementation of peak-peak electricity price, a related evaluation system is established. In the comprehensive evaluation system of this paper, the implementation effect of peak-peak electricity price is combed, and a suitable framework is established. The evaluation index is defined and the fuzzy analytic hierarchy process is used to evaluate. This evaluation mechanism can provide appropriate feedback information and provide effective supporting opinions to power companies, users and relevant government departments. It is of great significance to further improve the peak-peak price mechanism.
