Abstract

Energy consumption in India is rising rapidly mainly due to growth in economy and population. The only alternative to meet the ever rising demands of the nation is to tap the potential of renewable energy sources and promote Micro generation at the consumer's end. This approach ensures a greener energy with an added benefit of minimized transmission losses. In this paper an attempt has been made to envisage the impact of micro generation at the consumer's premises using renewable sources like solar and wind. In this approach only solar power is considered for computations which are injected during peak and off peak hours in order to reduce the power loss, thus improving the quality of power. This results in reduction of fossil fuel consumption. Power losses of various distribution networks are computed and the results are presented and analyzed. Cost benefit analysis is also carried out on two networks namely IEEE and Andhra Pradesh Eastern Power Distribution Corporation Limited (APEPDCL) to obtain the payback period of the investment.

Abstract

This paper presents an efficient and reliable Particle Swarm Optimization (PSO) algorithm for solving Reactive power optimization including voltage deviation in Power System. Voltage deviation is the capability of a power system to maintain up to standard voltages at all buses in the system under standard conditions and under being subjected to a disturbance. Reactive power optimization is a complex combinatorial programming problem that reduces power loses and improves voltage profiles in a power system. To overcome this shortcoming, a multi objective PSO is proposed and applied in reactive power optimization on IEEE-30 bus, Here the RPO problem has been formulated as a constrained multi-objective optimization problem by combining of two objective functions (real power loss and voltage profile improvement) linearly shows that the PSO more effectively solve the reactive power optimization problem in power system.

Abstract

To control the reactive power, voltage regulation is very difficult in power system from aspects of load compensation. Reduce the power losses and voltage improvement  as main aim to compute best setting of shunt devices such as shunt capacitors, SVC, tap changing transformers etc., in power system, when  load will gradually increased, then automatically voltage is not maintain reference value due inductive load and energy storage elements. In this paper proposed reduce the power losses and improve voltage profile by using SVC and , switched capacitors with co-ordination have been included in the system. The proposed system has been validated to 9-bus test system considered.
