An analytical approach for the sizing and siting of battery-sourced inverters in distribution networks

Heuristic optimisation‐based sizing and siting of DGs for enhancing resiliency of autonomous microgrid networks

“…technical, economic, and environmental (in case of renewables). Power loss minimisation, voltage regulation, improvement in system reliability and loadability, improved power quality, relieved transmission and distribution networks, and increased overall energy efficiency are among the major technical benefits of DGs [2]. Economic benefits of DGs includes saving world fuel, saving transmission, and distribution costs, and reducing wholesale electricity prices.…”

“…The objectives of the existing work on DG placement can be categorised as minimisation of power loss [1,2,[11][12][13][14][15][16][17], enhancement of voltage profile [1,2,[11][12][13][14][15][16][17], enhancement of system stability [18,19], improvement of loading margin [20], profit maximisation, and reduction of harmful emissions [21][22][23][24]. Both single objective [1,2,11,13,14,16,25] and multi-objective [20][21][22]26] functions have been used for optimal placement of DGs by different researchers. The popular methods used by different researchers for optimal siting and sizing of DGs are analytical approaches [2], mixed-integer non-linear programming [19], particle swarm optimisation (PSO) [13,14,16,17], genetic algorithms (GAs) [15,20,21], sensitivity analysis…”

“…Minimisation of both active and reactive power losses of the network has been considered by different researchers by placing DGs [1,2,[11][12][13][14][15][16][17]. In this paper, total loss (both active and reactive) has been considered for siting and sizing of DGs.…”

“…In this paper, total loss (both active and reactive) has been considered for siting and sizing of DGs. The total real power loss (P L ) of the system can be computed by using (1) and reactive power loss (Q L ) by (2), which are known as exact loss formulas. The single line diagram of two adjacent nodes (i and j) is shown in Fig. 1…”

“…Optimal siting and sizing of DGs are continuously being studied by researchers, applying different approaches and optimising various objective functions. The objectives of the existing work on DG placement can be categorised as minimisation of power loss [1, 2, 11–17], enhancement of voltage profile [1, 2, 11–17], enhancement of system stability [18, 19], improvement of loading margin [20], profit maximisation, and reduction of harmful emissions [21–24]. Both single objective [1, 2, 11, 13, 14, 16, 25] and multi‐objective [20–22, 26] functions have been used for optimal placement of DGs by different researchers.…”
