ABSTRACT
This chapter proposes expert systems (ES) for optimal loss reduction that uses a coordinated application for reconfiguration and Volt/VAr control in the distribution system. For this purpose, the ES improves a set of solutions proposed by an optimal power flow-based reconfiguration algorithm, executing reactive power control actions by capacitor bank commutations and regulator tap adjustments. In a dynamic electrical distribution system, the system operator must make decisions in real time to maintain the distribution system in an optimal operational state. If load variations or less severe failures occur, resulting in some overloads or voltages out of limits, then a transition from the normal to the emergency state occurs, and some corrective actions can be performed to restore the system to a normal operational state. Traditionally, reactive power control is performed to minimize losses and control voltages through capacitor bank switching and regulator tap adjustments.
