【摘要】：針對區(qū)域綜合能源系統(tǒng)在市場環(huán)境下的優(yōu)化調(diào)度中未充分考慮多個系統(tǒng)互聯(lián)及光伏/負(fù)荷的預(yù)測誤差等不確定性的現(xiàn)狀,研究基于區(qū)間線性規(guī)劃的區(qū)域綜合能源系統(tǒng)日前優(yōu)化調(diào)度方法。采用區(qū)間數(shù)對光伏出力及負(fù)荷的不確定性進(jìn)行區(qū)間描述,以能源服務(wù)公司利益最大化為目標(biāo),綜合考慮多能互補(bǔ)和網(wǎng)絡(luò)互聯(lián)及環(huán)境效益,并采用分時電價制度,建立基于區(qū)間線性規(guī)劃的區(qū)域綜合能源系統(tǒng)日前經(jīng)濟(jì)優(yōu)化調(diào)度模型,其目標(biāo)函數(shù)及優(yōu)化變量均以適宜區(qū)間來表示。采用強(qiáng)化區(qū)間線性規(guī)劃方法進(jìn)行求解,能夠保證解空間的絕對可行性。通過算例分析驗(yàn)證了該方法的可行性與合理性,仿真結(jié)果表明:在多個能源服務(wù)公司參與交易的背景下,區(qū)域綜合能源系統(tǒng)及配網(wǎng)的互聯(lián)可提高能源服務(wù)公司總盈利,區(qū)間形式的最優(yōu)解為決策者提供了選擇空間,可以反映系統(tǒng)中不確定因素對能源服務(wù)公司盈利的影響。
[Abstract]:In order to solve the uncertainty of multi system interconnection and the uncertainty of PV / load prediction error in the optimal scheduling of regional integrated energy system under the market environment, the daily optimization scheduling method for regional integrated energy system based on interval linear programming is studied. The uncertainty of interval number on PV output and load is adopted. Interval description, aiming at the maximization of Energy Service Companies benefits, considering multi energy complementarity and network interconnection and environmental benefits, and adopting time sharing price system, a daily economic optimal scheduling model of regional integrated energy system based on interval linear programming is established. The objective function and optimal variable are expressed in a suitable interval. This method can guarantee the absolute feasibility of the solution space. The feasibility and rationality of the method are verified by an example analysis. The simulation results show that the interconnection of regional integrated energy system and distribution network can improve the total profit of the Energy Service Companies under the background of multiple Energy Service Companies participation in the transaction. The optimal solution of the form provides the decision-maker with the choice space, which can reflect the influence of the uncertain factors on the Energy Service Companies's profit.
