Abstract
Increased electric energy demand is the major factor that cracks the researchers to focus on electrical energy demand to meet the challenge. Accordingly, the power loss should be minimized. Due to this, Distribution Flexible Alternating Current Transmission System (DFACTS) and Distributed Generation (DG) must be placed in an appropriate way in distribution systems. Fuzzy-Lightning Search Algorithm (FLSA) has been proposed to minimize the power loss in the radial distribution network by solving the optimal placement problem of Distribution STATic COMpensator (DSTATCOM) as DFACTS device and photo voltaic (PV) array unit as DG. The improved voltage profile values, less power loss and reduced stability problems have been attained by using FLSA. The proposed FLSA technique is evaluated through IEEE 30-bus system with MATLAB software. The power flow investigation has been done by Newton Raphson method. Optimum siting of DSTATCOM and PV array induced outstandingly decreased the losses to 7.0073 kW. The accomplished objectives and results have validated the FLSA is more advantageous than other optimization techniques.

Summary
The generation of electrical energy is inadequate to the customers, and it should be resolved. Renewable energy sources are used because of its abundancy and pollution-free nature. Optimal placement of DG is very important to reduce losses and solve power quality problems. Inappropriate DG placement will cause voltage stability problems and it leads to high power losses [1]. Proper placement of DG can improve voltage profile value, increased percentage of loss reduction and less operating cost [2]. By the consideration of environmental and economic aspects, optimal allocation of renewable-based DG and the location of energy pack up devices in distribution network have been proposed to reduce the operating cost and to reduce the environmental pollution [3]. Operating cost can be calculated by sampling methods by solving optimal power flow to place DG in a proper way [4]
