Determination of Optimal Allocation and Penetration Level of Distributed Energy Resources Considering Short Circuit Currents

Abstract

The integration of Distributed Energy Resources (DER) in the distribution network has plenty of advantages if their allocation and Penetration Level (PL) are done appropriately. Hence, the challenge of finding the best allocation and PL of DERs in large distribution networks is an important but intricate problem. This paper proposes a novel methodology to simultaneously determine the optimal location/capacity and PL of DERs based on both power losses and voltage deviation minimization, while constraints of voltage profile of feeders under light loading and short circuit capability of the CBs are met. Moreover, a Multi-Objective Mutation based PSO (MOMPSO) is presented that by introducing two modifications of dynamic inertia weight and utilizing a mutation operator improves exploration and exploitation searchability as well as convergence capability of the PSO algorithm. The proposed methodology is tested on a practical distribution network to evaluate its effectiveness in finding optimal location and capacity of DERs along with the feeders.

Resilient Operation of Electric Vehicles considering Grid Resiliency and Uncertainties

“…Comprehensive issues in DERs rescheduling weather impact on the failure rate of lines can be found in [25][26][27]. In the context of grid resilience improvement, various methods such as demand response programs (DRP), rescheduling of resources [28,29], DER utilization, network reinforcement, and reconfguration methods [30] have been proposed. However, in the matter of the CS, particularly integrated with DERs, developing an optimal and proportionate charging/discharging schedule can efectively improve network resilience.…”

Review of Different Methods for Siting and Sizing Distributed Generator

“…Distributed generator (DG) is a possible substitute for installing a new centralized generation station, particularly in the era of deregulation and it has several benefits such as low investment risk and short installation period (Gissey et al, 2021;Khaligh and Buygi, 2020;Martinez-Bolanos et al, 2020;Moret et al, 2020;Yang et al, 2020), modules with small capacity that can monitor variations in load very closely (Jiang et al, 2020;Mahmud et al, 2020;Somefun et al, 2020), small physical size suitable for installation at proximity to users' end, and availability of a large range of DG technologies (Nagaballi and Kale, 2020;Yang et al, 2021). However, it is important to note that when DGs are to be introduced into a distribution network, consideration should be to optimally site and size DG units otherwise, there will be an increase in power losses and a decrease in reliability levels (Balu and Mukherjee, 2020;Deb et al, 2020;Farzinfar et al, 2020;Galgali et al, 2021;Kizito et al, 2020;Manna and Goswami, 2020;Shuaibu et al, 2020;Truong et al, 2020). In recent time, there have been rise in the study of distributed generation in power system analysis.…”

Voltage Stability Improvement in Optimal Placement of Voltage Regulators and Capacitor Banks Based on FSM and MMOPSO Approach

“…Further, in some research, hybrid placement and sizing of SCBs/DGs to improve power losses and voltage profile of the distribution network and minimization of investment cost have been considered [11,[25][26][27]. To enhance the real Egyptian distribution system's performance, optimal placement of the combined SCBs, DGs, and VRs has been introduced in literature [28][29][30] based on the PSO algorithm.…”
