This paper presents a new approach for finding capacitor's location and it's sizing in a radial distribution system (RDS) optimally with an aim of reducing the active power loss. In this paper, the problem of minimizing power loss is converted into a Mixed Integer Non-Linear Program (MINLP) problem, and it will be solved by using Generalized Algebraic Modeling Systems (GAMS) software with MINLP-SBB Solver. The proposing GAMS approach is tested on IEEE 10 bus RDS. By using GAMS, the programming will be simple and more accurate results can be achieved with less execution time. The MATLAB R2020b is used to run the load flows program and analyze results. The results are compared with the other optimization techniques results.

“…Many important reactive power compensation technologies were reviewed in [7] in regard to methods used for load compensation and voltage support in power systems. Various approaches including Evolutionary Computational Techniques like Genetic Algorithm [8], [9], Particle Swarm Optimization [10], then Heuristic Optimization Technique [11], PDIPM [12] and other designed algorithms [13] and Volt/Var Optimization engines [14] have been developed to enhance Volt/Var control and optimization in the smart distribution grids of the future. An investigation of reactive power flows control through capacitor banks in distribution and industrial networks was proposed by authors in [15].…”

Voltage control in low voltage distribution networks continues to remain an issue of significant importance. The large portion of long overhead lines with high R/X ratio has been the main reason that these circuits were suffering from constant voltage fluctuations problems, especially during heavy load time period. In this paper, the effect of introducing distributed capacitors as potential voltage regulation technique, in the voltage profile and power losses in low voltage radial systems was investigated. Two circuits were selected from the existent Norwegian low voltage distribution grid for a profound analysis of voltage problems. The circuits are of different size with different load demand. The assessment was conducted for maximum, 50% and minimum load condition. The load flow was performed for the steady state of the system. The perceived approach seeks to maintain the voltage within satisfactory limits by compensating for reactive power at load terminals. The low voltage radial circuits were modeled using MATLAB/Simulink software and the load flow problem was solved using Graphical User Interface (GUI) toolbox. The obtained results showed the good performance of distributed capacitors to improve the voltage profile in the system.

“…For medium and high voltage transmission and distribution systems, the capacitor placement at the line is a common solution to recover the voltage profile back to normative limits. The practice has also been applied to low voltage distribution systems, attempting to their specific trade-offs [1][2][3][4][5], such as unaccepted voltage drop or line losses reduction.…”

he voltage profile of low voltage distribution systems must be in accordance to national regulations, usually given by a range in which voltage needs to be. Along a day, usually voltage fluctuates according to load characteristics, especially power level and power factor, and in some situations can overpass minimum acceptable values. This paper studies the influence of the power factor measurement point governing a DSTATCOM, over the feeder voltage profile. By simulation, it was saw that connecting the D-STATCOM at the end of the system, but correcting power factor saw by the initial pole, a better voltage compliance is obtained.
