Improving frequency regulation calculation in power grid integration with solar energy system

Abstract

Everyone requires uninterruptible, dependable power, and the power system must be able to handle the complexity that comes with so many people using power at once in modern times. The performance of the system can be improved in a variety of ways, including the use of flexible AC transmission system (FACTS) devices. FACTS controllers are power electronics-based controllers. This can be accomplished through series or shunt compensation. They either add or remove reactive power from the power system in response to changes in electricity demand. That’s why; flexible AC transmission system (FACTS) has been incorporated into the power system to increase the flexibility of power grids. A shunt type of FACTS controller, also known as Static Var Compensator (SVC), is investigated in this study to improve system stability and reduce the amount of loss that occurs in a nine-bus power system. A Thyristor Controlled Reactor (TCR), a Thyristor Switched Capacitor (TSC), a fixed capacitor coupled in parallel to the line, and filter components to reduce harmonics in the alternating current comprises the synchronous voltage conditioner (SVC). Voltage stability and loss reduction are investigated in terms of voltage variation as well as overall real and reactive power losses on each bus where the SVC is installed. This analysis determines whether SVC met its objectives. The load flow of a noncompensated system was then investigated. Finally, a load flow investigation was performed on a system that SVC compensated for by relocating the SVC installation from bus 1 to bus 9. Analyzing load flow data, voltage magnitude variation, and total losses can help determine the best location for the SVC. This aids in locating the SVC. This study contributes to achieving this goal. At every stage of the process, MATLAB/SIMULINK was used extensively in the performance study.
