摘要

随着分布式电源在配电网络中的渗透率不断提高及用电需求的日益增长，分布式电源及负荷具有的随机特性对配用电侧的安全可靠运行带来了新的挑战。为此，文中提出了一种考虑随机扰动影响的有源配电系统动态仿真方法。首先，根据分布式电源及负荷的随机特性，建立了光辐照度、风速、负荷波动的随机动态模型；其次，基于SUNDIALS提出了有源配电网随机动态仿真方法；最后，在中低压有源配电系统算例中进行了测试和验证。该方法与确定性仿真方法相比能够反映配电系统的不确定性，得到更真实的仿真结论。此外，利用SUNDIALS与并行计算策略，在满足了仿真数值精度的同时，提高了仿真效率。

Abstract

With the increasing penetration of distributed generators(DGs)and demand for electricity

the security and stability of distribution networks is facing new challenges due to the randomness of DGs and loads. A dynamic simulation method taking the stochastic disturbance influence into account is proposed for active distribution networks(ADNs). Firstly

stochastic models of the irradiance

wind speed and load fluctuations are developed to simulate the stochastic characteristics of DGs and loads. Then

a stochastic dynamic simulation method based on SUNDIALS is proposed. Finally

case studies based on a medium and low voltage ADN are performed to verify the proposed method. Compared with the deterministic simulation methods

the proposed method based on SUNDIALS and the parallel algorithm is better able to reflect the stochastic characteristics of ADNs while meeting the requirements of high simulation accuracy.
