This paper presents the design of secondary voltage control by tuning the parameters of coordinated PID controllers to eliminate voltage violations in power system contingencies. The coordinated PID control parameters are tuned by using genetic algorithm. The study is presented on modified IEEE 14 bus system. The coordinated secondary voltage control is assigned to the generators and STATCOMs in order...
In this paper, the Genetic Algorithm (GA) is used to calculate the available transfer capability in an optimal power flow environment. This algorithm is inspired by the Darwin's principle of reproduction and survival of the fittest. GA uses simple operators, such as reproduction, crossover, and mutation. The proposed method has been applied to real Indian 246-bus power system with an objective to...
Renewable energy, which is a continuous source of energy, can be classified as the sun, running water, biomass, wind, geothermal sources and ocean currents. Several research works projects about 30% of the total generations will be from Renewable Energy Sources (RES) in future and so it's important to analyze different prospects of RES mainly over distribution networks. In this paper, a new Distribution...
In this work, analysis and optimization of sliding-mode controller parameters are treated, in order to govern a static power converter. In this case, an ac–dc boost power factor corrector is used; generally, these kinds of converters are applied to obtain a power factor near to unity. Advantage that the designed controller can give is the improvement of dynamic and static performances in cases of...
The reactive power generation schedule in a power system determines the bus voltage profile. The available reactive power capabilities of the generators have to be optimally deployed so that bus voltages are kept within specified limits. While applying the standard power flow algorithms, the voltage and real power injection are set for a generator bus. After running the power flow analysis, or while...
This paper studies the design of reactive power supply for microgrids. The problem can be stated as follows: for a given microgrid, determine an optimum allocation of reactive power sources so that adequate voltages can be maintained during islanded mode as well as more than one topology of islanded operation. A genetic algorithm is used to develop the optimal allocation
