“…For last two decades artificial intelligence techniques are widely used to find the optimal size and location of capacitor. Sarfraz et al [6] proposed a technique for determining the size and location of shunt capacitor, used PVSC for determining the location and size of shunt capacitor. The results obtained were associated with previous practices.…”

The distribution system in power system have high resistance to reactance ratio therefore it provides more power losses and voltage drop issues. Furthermore, the load used in distribution side is mostly of inductive in nature and gives reactive power losses. Therefore, an attempt is made to integrate shunt capacitor banks to improve reactive power losses and to maintain the voltage profile in the allowable limit. Moreover, the proposed model is tested on 11kV Hyderabad Electric Supply Corporation (HESCO) distribution feeder for analysis of reactive power. An artificial intelligence technique named as particle swarm optimization (PSO) is used to identify the optimal placement of shunt capacitor. The proposed method reduces more than 40 % power losses and gives better results in voltage profile (i.e. more than 0.95 p.u.) at all buses.

“…Cost function for sizing and location of capacitors is based on cost for investment problem of own capacitors (Z 1 ), cost for power loss in own capacitors (Z 2 ) and cost for power loss in whole system after compensating (Z 3 ) [7], [10], [11], [12], [13], [14].…”

“…Each sizing of shunt capacitors can make change of the power flow and all operational parameters in whole power system. The problem of optimal sizing and location of shunt capacitors has been solved by technical and cost factors [5] [6] [7]. The cost factor can help to evaluate the cost for purchasing capacitors, power loss in own capacitors and whole system after compensating when the load varies or not [5], [8].…”

-This paper introduces a method to determine optimal sizing and location of shunt capacitors in medium voltage Underground Power Cables or in distribution system. To execute this method, two models of standard branch and the Newton-Raphson method are also mentioned to analyze and determine values of bus voltage and currents going through lines in whole system. The EN 50160 standard is introduced to evaluate all operational parameters and propose solutions to reduce risks. In additionally, the cost function method is introduced basing on cost of purchasing compensative device, power loss in own compensators and whole system after compensating. By considering partial derivative of cost function with respect to variables, optimal sizing and location of shunt capacitors can be determined for all buses in the system. Analyzing the system by using the Newton-Raphson method in stable mode, all operational parameters are evaluated to see the benefit of placing capacitors in some criterions: reduce the current going through all lines and increase value of bus voltage in whole system. Theory research is verified by simulation results carried out in Matlab 2016 software.
