    OPTIMAL SITING AND SIZING OF SSSC IN INPS USING MODIFIED SALP SARM ALGORITHM CONSIDERING OPTIMAL REACTIVE POWER DISPATCH PROBLEM
    (I.O.E, 2024-06) Karna, Priyanka; Chaudhary, Jeetendra
    In a power system, effective coordination between generation and demand is crucial. With the growing demand for electrical energy, optimizing the operation of all components to maximize efficiency becomes imperative. FACTS devices are essentially tools designed to enhance the efficiency of the transmission system. In a power system network, these devices are employed to enhance the power transfer capacity of transmission lines. Their utilization results in improved voltage stability, transient stability, voltage regulation, reliability, and increased thermal limits within the transmission network. The Static Synchronous Series Compensator (SSSC) is a method of series compensation applied in the transmission system. Its purpose is to either raise or lower the voltage drop along the line, thereby managing the power flow through the transmission line. By introducing voltage in quadrature with the line current, the SSSC regulates the power flow by controlling the equivalent impedance of the transmission line. The SSSC's output voltage is entirely controllable and operates independently of the line current. The Optimal Reactive Power Dispatch (ORPD) problem is tough because of non linear and non-convex functions. Addition of SSSC makes the solution even harder by bringing in complex dynamics for controlling power flow. To deal with these challenges, we need smart techniques and computer methods to find good solutions with efficient and reliable optimization algorithm to solve the problem of ORPD and identify the optimal location and rating of SSSC. In this thesis, Modified Salp Swarm Algorithm is used to solve the ORPD with and without the SSSC controller to minimize power losses and voltage deviations as well as improve the voltage stability on the Intergrated Nepal Power System (INPS) system and hence the result is compared with the standards IEEE 30-bus system. After solving the ORPD problem and load flow analysis, initial line losses of 119.108 MW (5.8% of total load) reduced to 35.336
