STEADY-STATE ANALYSIS OF NIGERIA 330 KV POWER NETWORK UNDER STATCOM AND SOLAR PV SUPPORT

Abstract: Nigeria's 330 kV transmission grid still grapples with operational issues like voltage instability and high transmission losses quite frequently nowadays. Integrating Static Synchronous Compensator and solar photovoltaic systems profoundly affects steady-state conditions on weak buses within Nigeria's 48-bus grid infrastructure. Simulations were run with MATLAB and Power System Analysis Toolbox under four distinct scenarios namely base case, STATCOM only, PV only, and combined STATCOM with PV. Results show combined deployment drastically improved bus voltages at Birnin Kebbi Akangba Lekki Aladja and Alaoji from as low as 0.89 pu. Line loading at weak buses decreased substantially from over 90 percent below 75 percent and available transfer capability rose sharply by nearly 29 percent. Total system power loss decreased substantially from 42.5 MW under base case conditions and settled at 28.6 MW with combined support. Hybrid STATCOM and solar PV integration remarkably bolsters voltage stability and system efficiency within Nigeria's transmission grid quite effectively. Keywords: Available transfer capability, Nigeria transmission grid, solar photovoltaic, STATCOM, voltage stability.
