When a number of capacitors are connected together it forms a capacitor bank. They can be connected in series or parallel. A capacitor bank has numerous advantages and applications. Most of the time, these are used for reactive power compensation and power factor improvement. The arrangement of these can be done at substation or power plants.
The capacitor model adopted in the LF is not ideal: to take into account the internal losses, an active power for the capacitor bank is considered equal to 0.5% of the reactive power. All nodes are eligible for capacitor placement ( ). Table 5. Capacitor bank unit data adopted in the case study.
When a number of capacitors are connected together in series or parallel, forms a capacitor bank. These are used for reactive power compensation. Connecting the capacitor bank to the grid improves reactive power and hence the power factor. As shown in the figure, capacitors are connected in series to improve the power factor rating.
We have seen that a capacitor bank is used for the improvement of power factor and reactive power compensation in a substation. As the role of this bank is very important, it becomes critical to see that the bank is maintained well. Also, it has to be seen which parameters of this bank should be specified for installing it into the substation.
In this context, a genetic algorithm is proposed for optimal planning of capacitor banks. A case study derived from a real network, considering the application of suitable daily profiles for loads and generators, to obtain a better representation of the electrical conditions, is discussed in the present paper.
Therefore, the capacitor bank units are calculated as in Equation (1), where is the cost (in $) for the capacitor bank with nominal power equal to (in MVar) and placed in a node with nominal voltage (in kV), while is a lifespan for the same unit (in years); the cost is calculated for all N candidate nodes (if ).
