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.

In [26, 27, 28], researchers focus on improving capacitors in electrical systems to minimize the power line failure rate after capacitor installation. In [29, 30], the phenomena of transient switching events and their impact on the system are discussed.
Limit of Capacitors The reactive power of all capacitors placed in a system must be limited as the following inequality: where Qcapc is the generation of the c th capacitor; and is the maximum generation of all capacitors.
For compensating reactive power, shunt capacitors are often installed in electrical distribution networks. Consequently, in such systems, power loss reduces, voltage profile improves and feeder capacity releases. However, finding optimal size and location of capacitors in distribution networks is a complex combinatorial optimisation problem.
In this paper, a new method of reactive power compensation is proposed for reducing power loss of distribution power networks. The new method is the combination of local compensation at each load and distribution line compensation.
