Optimization for Alternative Schemes of Black Start Power Sources Considering Water Reserve of Hydropower Station

doi:10.16182/j.issn1004731x.joss.201701023

Abstract

Abstract: An optimization method was proposed to determine alternative schemes of the hydropower black start sources, by considering water reserve constraints. A pumped storage power station was employed to crank some thermal units close to the pumped storage and was with good start-up performance. The restarted thermal units were used as power sources for subsequent restoration instead of the pumped storage units. The reliability of restoring units, the total capacity of selected units and units' node importance in network were defined as objective functions of the optimization problem. The immune algorithm was employed to search for the Pareto optimal solution set of the feasible schemes. The grey correlation model was applied to identify satisfactory solution from the solution set. The effectiveness of the proposed method was validated by simulation results.

Key words: power system restoration, black start power source, reservoir storage, alternative power source
