Those techniques were applied to the small scale power system (.6 nodes system), and we showed an appropriateness of DC method. In this paper, appling this DC method to the actual power systems (IEEE 21, 30, 57, 118 nodes systems), and comparing the calculated results with those of optimization technique using Newton-Raphson method, we show that the larger power systems, the more appropriateness we can get by DC method in the aspects of memory domain and computing time.}, pages = {151--160}, title = {電力潮流の最適化 (第4報)* -実規模系統への適用例-}, volume = {9}, year = {1978} }
