【摘要】:針對智能配電網(wǎng)中分布式電源(DG)接入及電網(wǎng)仿真實(shí)時(shí)響應(yīng)的需求,提出一種分布式并行環(huán)境下求解智能配電網(wǎng)中各DG最優(yōu)輸出功率的方法,實(shí)現(xiàn)了快速高效的配電網(wǎng)電壓優(yōu)化。該方法首先基于凝聚層次聚類法(HAC),解決了智能配電網(wǎng)自動(dòng)分區(qū)的問題,在此基礎(chǔ)上,采用分布式序列二次規(guī)劃(DSQP-DG)算法,通過內(nèi)外層迭代交替并行求解出DG最優(yōu)出力。以接入DG的IEEE 33節(jié)點(diǎn)系統(tǒng)算例對該方法進(jìn)行測試驗(yàn)證可知,較之輔助問題原理(APP)方法,該方法具備更好的尋優(yōu)能力和快速性,能夠有效解決智能配電網(wǎng)分布式并行電壓優(yōu)化問題。
[Abstract]:In order to meet the demand of (DG) access of distributed generation and real-time response of power network simulation in smart distribution network, a method to solve the optimal output power of DG in smart distribution network under distributed parallel environment is proposed. A fast and efficient distribution network voltage optimization is realized. Firstly, this method solves the problem of intelligent distribution network automatic partition based on (HAC), and then uses distributed sequential quadratic programming (DSQP-DG) algorithm. The optimal output force of DG is solved by alternating iteration of inner and outer layers in parallel. An example of IEEE 33-bus system connected to DG is used to test and verify the method. Compared with the auxiliary problem principle (APP) method, this method has better optimization ability and rapidness. It can effectively solve the problem of distributed parallel voltage optimization in intelligent distribution network.
