Abstract: Solar energy has become a chief source of energy with the advancements in PV cell efficiency and reduction in cell cost, grid-connected photovoltaic systems does not require bulk and lossy battery bank. High voltage Distributed generation and on-site supply of PV system minimizes distribution losses, and mitigates environment pollution. In this, the robust solar power system stabilizer (RPSS) is designed using enhanced ABC for designing the controllers for dynamical systems in electrical engineering. Comparisons are also made between the Conventional power system stabilizer (CPSS), PSS with H8 optimization and PSS with PSO optimization. Experimental results show that compare to other techniques, enhanced ABC is more effective to produce desired response.

Keywords: RPSS, CPSS, H8, PSO, Enhanced ABC.
