Abstract

Contemporarily, the development of distributed generations (DGs) technologies is fetching more, and their deployment in power systems is becoming broad and diverse. Consequently, several glitches are found in the recent studies due to the inappropriate/inadequate penetrations. This work aims to improve the reliable operation of the power system employing reliability indices using a metaheuristic-based algorithm before and after DGs penetration with feeder system. The assessment procedure is carried out using MATLAB software and Modified Salp Swarm Algorithm (MSSA) that helps assess the Reliability indices of the proposed integrated IEEE RTS79 system for seven different configurations. This algorithm modifies two control parameters of the actual SSA algorithm and offers a perfect balance between the exploration and exploitation. Further, the effectiveness of the proposed schemes is assessed using various reliability indices. Also, the available capacity of the extended system is computed for the best configuration of the considered system. The results confirm the level of reliable operation of the extended DGs along with the standard RTS system. Specifically, the overall reliability of the system displays superior performance when the tie lines 1 and 2 of the DG connected with buses 9 and 10, respectively. The reliability indices of this case namely SAIFI, SAIDI, CAIDI, ASAI, AUSI, EUE, and AEUE shows enhancement about 12.5%, 4.32%, 7.28%, 1.09%, 4.53%, 12.00%, and 0.19%, respectively. Also, a probability of available capacity at the low voltage bus side is accomplished a good scale about 212.07 times/year.

基于元启发式算法的集成系统可用性容量评估与可靠性评估

当前，分布式发电技术的发展越来越受到重视，其在电力系统中的应用也越来越广泛和多样化。因此，在最近的研究中，由于不适当/不充分的渗透，发现了一些小故障。本文旨在利用基于元启发式算法的可靠性指标，提高dg与馈线系统渗透前后电力系统的可靠运行。利用MATLAB软件和改进的Salp群算法(MSSA)对所提出的集成IEEE RTS79系统在7种不同配置下的可靠性指标进行了评估。该算法修改了实际SSA算法的两个控制参数，在探索和开发之间取得了很好的平衡。此外，利用各种可靠性指标对所提方案的有效性进行了评估。此外，根据所考虑的系统的最佳配置计算扩展系统的可用容量。结果证实了扩展后的DGs与标准RTS系统的可靠运行水平。具体来说，当DG的1号线和2号线分别与9号线和10号线连接时，系统的整体可靠性表现出优越的性能。本病例的信度指标SAIFI、SAIDI、CAIDI、ASAI、AUSI、EUE和AEUE分别提高了12.5%、4.32%、7.28%、1.09%、4.53%、12.00%和0.19%。此外，低压母线侧可用容量的概率达到了约212.07次/年的良好规模。
