Multi-objective optimal power flow considering the multi-terminal direct current

Introduction. In recent years, transmission systems comprise more direct current structures; their effects on alternating power system may become significant and important. Also, multi-terminal is favorable to the integration of large wind solar plants with a very beneficial ecological effect. The novelty proposed work consists in aforementioned modern devices transient stability, thus turn out be an interesting research issue. our view, they constitute new challenge additional complexity for studying dynamic behavior electrical systems. Purpose. We sought resolution problem stability constrained optimal flow / meshed networks. Convergence security has been globally achieved. Methods. solution was carried MATLAB environment, by iterative combinatorial approach between optimized computation simulation. Results. A considering can improve after contingency occurrence operate economically within physical bounds. Practical value. effectiveness robustness method tested modified IEEE 14-bus test multi-objective optimization that reflect active generation cost minimization It should mentioned losses are small networks relative standard network. led gain up 46,214 % from base case.
