“…Meanwhile, deregulation and market liberalization have promoted the decentralization of power systems [16][17][18][19], and therefore, technology development for maintaining local area power quality in the distribution system is required [20][21][22]. With the improvements in required management technology, fundamental functionalities in the system operation, such as the demand forecast [23], state estimation [24,25], visualization [4,26,27] and system security [28][29][30][31][32][33][34][35], have been developed. These basic technologies have contributed to the foundation of advanced energy management systems in the current distribution networks [36][37][38][39].…”
