【摘要】：微電網(wǎng)中形式各異的分布式電源使其在動(dòng)態(tài)響應(yīng)上體現(xiàn)為多時(shí)間尺度特征,其穩(wěn)定性仿真算法在數(shù)值穩(wěn)定性和計(jì)算效率方面需要滿(mǎn)足更高的要求。本文提出一種基于投影積分算法的微電網(wǎng)穩(wěn)定性仿真方法,每一個(gè)投影積分步由若干小步長(zhǎng)積分步(內(nèi)部積分器)和一個(gè)大步長(zhǎng)積分步(外部積分器)組成,仿真步長(zhǎng)及投影步長(zhǎng)可根據(jù)系統(tǒng)快、慢動(dòng)態(tài)響應(yīng)的時(shí)間常數(shù)選取,可有效實(shí)現(xiàn)傳統(tǒng)顯式積分算法數(shù)值穩(wěn)定性的提升,且為2階精度算法。以一個(gè)低壓微電網(wǎng)為例,通過(guò)與商業(yè)仿真軟件的仿真結(jié)果進(jìn)行比較,驗(yàn)證了算法的正確性和有效性。
[Abstract]:The dynamic response of distributed generation in microgrid is characterized by multiple time scales, and its stability simulation algorithm needs to meet higher requirements in terms of numerical stability and computational efficiency. In this paper, a simulation method of microgrid stability based on projection integral algorithm is proposed. Each projection integral step consists of several small step integral steps (internal integrator) and a large step size integral step (external integrator). The simulation step size and the projection step size can be selected according to the time constant of the fast and slow dynamic response of the system, and the numerical stability of the traditional explicit integral algorithm can be improved effectively, and the algorithm is of second order accuracy. Taking a low-voltage microgrid as an example, the correctness and validity of the algorithm are verified by comparing the simulation results with commercial simulation software.
