Among the 30 capacitor allocation scenarios, the lowest losses and costs are attained by allocating three capacitors with 600 kvar, as shown in Fig. 8. Variation in the costs against the number of capacitors: a normalized costs of capacitors and losses, b normalized total cost
The total cost consists of two factors, including the lifecycle cost of capacitors as well as the system's energy loss during the lifespan of capacitors. Thus, the capacitor banks should at least compensate for the lifecycle cost by decreasing the loss cost. The lifecycle cost includes installation, O&M, and purchasing (namely kVar) costs.
The base sizes of the capacitor banks are different and are obtained based on minimizing the cost function. In this study, the costs of unit energy loss, installation, O&M, and purchasing costs are considered $0.06/kWh, $1000, $600/year, and $3/kVar, respectively.
To calculate the lifecycle cost of capacitors, the equivalent size of capacitors (namely $Size ( n )$ ) is considered to better adapt to the next stage. This is because, in the next stage, each capacitor is a base size multiplied by a coefficient from 0 to 10.
Capacitor allocation in unbalanced systems has been investigated in [9 - 11], through a two-stage approach, for optimal location and optimal sizing, under loss minimization , using a hybrid honey bee colony algorithm , and based on using different load models under a penalty-free genetic algorithm .
NOS, number of switching. In summary, the decision variables are optimal locations (namely buses) and optimal base sizes (which are multiplied by 0–10 for optimal switching) of capacitors. The other important results are optimal lifecycle cost, gross saving, and net saving.
