The main objective of the presented work is to explore DSTATCOM, UPFC, and DPFC for mitigation of voltage sag/swell and improvement of power quality, to test their potential for single and multi-generator (power plant) system, effects of faults on adjacent lines in single generator system and multi-generator system. The high demand of electrical power distribution especially in India where it is targeted to have electrical power supply to every village, the non-linear load dynamics, extreme environmental conditions and increased harmonics simultaneously raised the demand for optimization in power losses, optimal power supply regulation, and mitigation of harmonic distortions. The integration of renewable energy sources on large scale and introduction of smart grids also needs transient state and steady state controllability enhancement and hence the work investigates the suitability and superior power electronic control for the power transmission and distribution systems. The presented work also investigates the impact of faults on adjacent lines, the dynamic instability due to integration of new power sources, future scope for integration of automation in power distribution and transmission system.
