Based on flexible adjustment capability of ADN, a multiobjective Bibilevel programming model about distribution generation considering active management mode was proposed in this paper. The objective of upper level model was to minimize the total life cycle cost of power supply side in the system, thus the installation and configuration plan was obtained after optimization. Whereas the lower level model was aimed at minimizing active power curtailment value, and operation optimization of distributed generation (DG) was obtained through applying DG output control, onloadtapchanging transformer adjustment, reactive power pensation device adjustment and other active management modes. The upper and lower model weremodels were solved by improved particle swarm optimization (PSO) algorithm with adaptive mutation, which could improve the solution speed and the global optimal effectiveness. Besides, the simulation analysis of the IEEE 33node system was carried out to verify the rationality of the model.Keywords: active management, multiobjective bilevel planning, distributed generation, improved particle swarm optimization optimizationalgorithm0 引 言電源規(guī)劃是配電網(wǎng)規(guī)劃中的一個至關(guān)重要的環(huán)節(jié),其涉及到負(fù)荷預(yù)測、電力電量平衡、廠址選擇、機組類型和規(guī)模、燃料來源及運輸條件、系統(tǒng)運行、網(wǎng)絡(luò)規(guī)劃和各種技術(shù)經(jīng)濟指標(biāo)的選擇等一系列問題[1]。隨著能源問題日益嚴(yán)重,可再生分布式電源(RES)的興起順應(yīng)了節(jié)能減排的要求,并得到廣泛應(yīng)用與發(fā)展。然而,當(dāng)前DG接入配電網(wǎng)仍采用“安裝即忘記”的被動管理模式,沒有充分考慮不可控DG出力的間歇性和隨機性對電網(wǎng)造成的不利影響,同時也未充分發(fā)揮DG靈活調(diào)控對于降低網(wǎng)損、改善支路潮流等方面的積極作用。主動配電網(wǎng)模式的提出解決了優(yōu)化利用DER的問題,利用主動管理和主動控制的方式進行分散管理、靈活控制網(wǎng)絡(luò)結(jié)構(gòu),可以實現(xiàn)DG與配電網(wǎng)的充分集成并提升DG的滲透容量[23]。在傳統(tǒng)配電網(wǎng)環(huán)境下的DG優(yōu)化配置問題中,中壓配電網(wǎng)往往作為電力系統(tǒng)的被動負(fù)荷,在無故障情況下不會自動操作,因此其網(wǎng)架結(jié)構(gòu)較為固定。文獻[4]以最小化含環(huán)境效益的DG投資成本及運行成本為優(yōu)化目標(biāo),建立了DG優(yōu)化配置模型,分析了風(fēng)速、天然氣價格以及污染物排放處罰標(biāo)準(zhǔn)等三個變量對確定DG最優(yōu)配置方案的影響
