【摘要】：隨著分布式電源在配電網(wǎng)絡(luò)中的滲透率不斷提高及用電需求的日益增長,分布式電源及負荷具有的隨機特性對配用電側(cè)的安全可靠運行帶來了新的挑戰(zhàn)。為此,文中提出了一種考慮隨機擾動影響的有源配電系統(tǒng)動態(tài)仿真方法。首先,根據(jù)分布式電源及負荷的隨機特性,建立了光輻照度、風速、負荷波動的隨機動態(tài)模型;其次,基于SUNDIALS提出了有源配電網(wǎng)隨機動態(tài)仿真方法;最后,在中低壓有源配電系統(tǒng)算例中進行了測試和驗證。該方法與確定性仿真方法相比能夠反映配電系統(tǒng)的不確定性,得到更真實的仿真結(jié)論。此外,利用SUNDIALS與并行計算策略,在滿足了仿真數(shù)值精度的同時,提高了仿真效率。
[Abstract]:With the increasing permeability of distributed generation in distribution network and the increasing demand for electricity, the random characteristics of distributed generation and load bring new challenges to the safe and reliable operation of distribution side. In this paper, a dynamic simulation method for active power distribution system considering random disturbance is proposed. Firstly, a stochastic dynamic model of light irradiance, wind speed and load fluctuation is established according to the stochastic characteristics of distributed power generation and load. Secondly, a stochastic dynamic simulation method for active distribution network based on SUNDIALS is proposed. Finally, the test and verification are carried out in the example of medium-low voltage active distribution system. Compared with the deterministic simulation method, this method can reflect the uncertainty of the distribution system and obtain more realistic simulation results. In addition, using SUNDIALS and parallel computing strategy, the simulation accuracy is satisfied and the simulation efficiency is improved.
