【摘要】:針對微網(wǎng)中源儲荷的協(xié)同配置問題,為確保微網(wǎng)系統(tǒng)的經(jīng)濟(jì)性,在規(guī)劃階段需細(xì)致考慮源儲荷的配比問題。提出了基于雨流計(jì)數(shù)法的電池健康狀態(tài)評估方法,考慮儲能電池健康狀態(tài)(state of health,So H),以源儲荷凈收益最大為目標(biāo),提出了電池儲能系統(tǒng)各時(shí)段充放電功率的優(yōu)化方法,綜合考慮了運(yùn)行效益、補(bǔ)貼及上網(wǎng)收益、延緩配電網(wǎng)升級帶來的效益、碳減排效益、投資運(yùn)維及電池替換成本,以投資回報(bào)率為指標(biāo),建立了源儲荷的協(xié)同配置模型,并提出了一種雙層多目標(biāo)優(yōu)化求解方法,通過實(shí)際算例仿真分析,結(jié)果表明:所提出的源儲荷協(xié)同配置方法能夠?qū)崿F(xiàn)微網(wǎng)系統(tǒng)的經(jīng)濟(jì)性,該文算例中,光儲荷的適宜配比為0.7:0.125:1,儲能系統(tǒng)持續(xù)放電時(shí)間為3 h,源儲荷的協(xié)同配置受電價(jià)、負(fù)荷、收益構(gòu)成、光儲成本、儲能技術(shù)特性等多因素制約。仿真結(jié)果證明了模型及其求解方法的有效性,可為微網(wǎng)中源儲荷的協(xié)同配置提供參考。
[Abstract]:In order to ensure the economy of the source storage in the micro network, in order to ensure the economy of the microgrid system, the proportion of the source and storage in the planning stage should be carefully considered. A method of evaluating the health state of the battery based on the rain flow counting method is put forward, considering the health state of the energy storage battery (state of health, So H), and the goal of the maximum net return of the source is proposed. The optimization method of charging and discharging power in each period of the battery energy storage system has taken into account the efficiency of operation, the benefit of subsidies and Internet access, the benefit of postponing the upgrading of the distribution network, the benefit of carbon emission reduction, the cost of investment and maintenance and the replacement cost of the battery. The cooperative configuration model of the source storage charge is set up with the return on investment as the index, and a double layer multi-objective optimization is put forward. The result shows that the proposed method can realize the economy of the microgrid system. In this example, the appropriate proportion of the storage load is 0.7:0.125:1, the continuous discharge time of the energy storage system is 3 h, the cooperative configuration of the source storage system is subject to the electricity price, the load, the income composition, the storage cost, and the storage cost. The simulation results prove the validity of the model and its solution method, and provide a reference for the collaborative allocation of source and storage in microgrid.
