Optimal Capacitor Placement for IEEE 14 bus system using Genetic AlgorithmAM Publications
Genetic Algorithm (GA) is a non-parametric optimization technique that is frequently used in problems of combinatory nature with discrete or continuous variables. Depending on the evaluation function used this optimization technique may be applied to solve problems containing more than one objective. In treating with multi-objective evaluation functions it is important to have an adequate methodology to solve the multiple objectives problem so that each partial objective composing the evaluation function is adequately treated in the overall optimal solution. In this paper the multi-objective optimization problem is treated in details and a typical example concerning the allocation of capacitor banks in a real distribution grid is presented. The allocation of capacitor banks corresponds to one of the most important problems related to the planning of electrical distribution networks. This problem consists of determining, with the smallest possible cost, the placement and the dimension of each capacitor bank to be installed in the electrical distribution grid with the additional objectives of minimizing the voltage deviations and power losses. As many other problems of planning electrical distribution networks, the allocation of capacitor banks are characterized by the high complexity in the search of the optimum solution. In this context, the GA comes as a viable tool to obtaining practical solutions to this problem. Simulation results obtained with a electrical distribution grid are presented and demonstrate the effectiveness of the methodology used.

2. Introduction
Load flow studies or Power flow studies is the analysis
of a power system in normal steady state condition.
Load flow studies basically comprises of the
determination of
Voltage
Current
Active Power
Reactive Power
3. Importance
Generation supplies demand(Load) plus losses.
Bus voltage magnitude remain close to rated value.
Generation operates within specified real and reactive
power limits.
Transmission line and transformer are not overloaded.
4. Need of Load flow study
Designing a power system.
Planning a power system.
Expansion of power system.
Providing guide lines for optimum operation of power
system.
Providing guide lines for various power system studies.
5. Bus Classification
A bus is a node at which many Transmission lines, Loads
Generators are connected.
It is not necessary that all of them be connected to every
bus.
Bus is indicated by vertical line at which no. of
components are connected.
In load flow study two out of four quantities specified
and other two quantities are to be determined by load
flow equation.
Depending upon that bus are classified.
7. Load bus or PQ Bus
A buss at which the Active power and reactive power
are specified.
Magnitude(V) and phase angle(δ) of the voltage will
be calculated.
This type of busses are most common, comprising
almost 80% of all the busses in given power system.
8. Generator bus or P-V bus
A bus at which the magnitude(V) of the voltage and
active power(P) is defined.
Reactive power(Q) and Phase angle(δ) are to be
determined through load flow equation.
It is also known as P-V bus.
This bus is always connected to generator.
This type of bus is comprises about 10% of all the
buses in power system.
9. Slack Bus
Voltage magnitude(V) and voltage phase angle(δ) are
specified and real(P) and reactive(Q) power are to be
obtained.
Normally there is only one bus of this type is given in
power system.
One generator bus is selected as the reference bus.
In slack bus voltage angle and magnitude is normally
considered 1+j0 p.u.
11. Static method
The following variables are associated with each bus:
Magnitude of voltage(V)
Phase angle of voltage(δ)
Active power(P)
Reactive power(Q)
The load flow problem can solved with the help of
load flow equation(Static load flow equation).
12. Continue
The bus admittance matrix is given by:
In general the equation for bus-1 can be written as:
Y11V1+Y12V2+Y13V3=I1
For bus-2 and bus-3 we can write:
Y21V1+Y22V2+Y23 V3=I2
Y31V1+Y32V2+Y33 V3=I3
13. Continue
So Ii=∑ Yik Vk where i,k=1,2,…,n
So complex power is denoted as
14. Continue
In polar form we can write
The equation is written as:
Real and reactive power expressed as:
15. Approximate method
A simple and approximate solution can be made by
following assumption:
1. Small line resistance are neglected which means
active power loss in line is zero i.e. θik ~ 90 ˚
2. Voltage magnitude at various must be within limits.
3. Active and reactive generator power at different
buses must be within the limits.
16. Continue
4. Total power generation must be equal to load plus
losses.
5. The system stability consideration impose a limit on
maximum values with δ.
6. All buses other than slack bus are PV buses. i.e. voltage
magnitude at all the buses, Including the slack bus, are
specified.
7. The angle δi so small that (sin(δi))= δi.
