Chapter 29 - Reactive power compensation for voltage variation mitigation in grid with renewable energy

Abstract

Grid integration of renewable energy (RE) power in the network transmission utilities creates problems of voltage variations. This is due to the requirement that the power is to be utilized as and when generation is available from the RE power plants. Further, the uncertain and variable nature of the RE generations also affects the voltage quality in the network of utility grids. This can be mitigated by the optimal use of the reactive compensation using the reactors and capacitors. This study has proposed the planning of static and dynamic reactors (TCR) to overcome the problems of overvoltages in the transmission system of Rajasthan state of India. This network has complex network transmission lines and grid substations (GSS) rated at voltage levels of 132, 220, 400, and 765kV where the conventional and RE generators are integrated to this network. The study of reactive power compensation is performed using the MiPower software where the transmission network of the Rajasthan State of India is modeled.
