How a capacitor is calculated based on power factor?

In the first step, given power factor of each load node is predetermined and then capacitor at the load node is calculated based on the known power factor, active power, and reactive power of the load. In the second step, the total compensation power of all capacitors at electric loads is determined.

Which radial distribution systems are considered for capacitor placement?

In this section, four radial distribution systems with 15, 33, 69, and 85 buses are considered for capacitor placement. In the first stage, reactive power compensation at each load in the systems is implemented for increasing the power factor into 0.9.

How to place capacitors in a distribution line?

Three methods including PSO, PPA, and TSA are applied to place capacitors in the distribution lines. Similar to the two systems above, Case 1 with the placement of two capacitors and Case 2 with the placement of three capacitors in distribution lines are executed and discussed in the following sections.

What is a centralized reactive power compensation system?

Abstract: A centralized reactive power compensation system is proposed for low voltage (LV) distribution networks. It can be connected with any bus which needs reactive power. The current industry practice is to locally install reactive power compensation system to maintain the local bus voltage and power factor.

How to select the maximum generation of all capacitors?

Consequently, the maximum generation of all capacitors can be selected as follows: 3. Tunicate Swarm Algorithm (TSA) In the paper, three metaheuristics are applied, that is, PSO, PPA, and TSA. However, PSO is one of the earliest methods that has been used in many studies and PPA is not more effective than TSA.

How do capacitors increase power factor of load?

In the method, local capacitors at each load are determined to increase power factor of load to an expected value first and then a number of capacitors are placed in distribution lines with two factors, location and capacity by using the three applied methods.
