This paper presents an efficient and reliable new invasive weed optimization algorithm to solve scheduling of hydro-thermal systems with cascaded reservoirs. A multi chain cascaded hydro-thermal systems with non-linear relationship between water discharge rate, power generation and net head is considered. The water transport delay between cascaded reservoirs, prohibited operating zones, valve point loading effects and transmission losses are also considered. The feasibility of the proposed method is demonstrated in one standard test system consisting of four cascaded hydro units and an equivalent thermal unit. The findings of the proposed method are better than the results of other established methods reported in literature in terms of quality of solution and convergence characteristics.
