Improve Reliability

Distribution system is the final stage of electric power system, and can be classified based on voltage level, location, number of wires, and types of customers. This chapter explains the various classifications of the distribution system in detail. System reliability is one of the important design concerns for any distribution system. The various methods of design concept to improve reliability are clarified. Reactive power compensation is another main concern in a distribution system. Methods of reactive power compensation are also detailed.

This paper discusses the use of centralized control method in an Intelligent Energy Management System (iEMS) to prevent voltage violation after load transfer between distribution feeders with high PV penetration level. The proposed method comprises three control modes with different control algorithms for regulating both reactive and active power output of PV inverters in a distribution system with multiple PV installations. Before the execution of load transfer, the total reactive power compensation required at the critical Point of Common Coupling (PCC) is solved by the reactance of distribution feeder line segment to prevent system voltage violation. With the proposed control algorithms, the iEMS dispatches total reactive power compensation among PV systems according to the reactance of line segment and issues the control command to each PV inverter for adjustment of PV power generation so that the ancillary service of voltage support can be provided by all PV systems in a fairer manner. A practical Cimei island distribution feeder pair is selected for computer simulation to verify the effectiveness of the proposed control method after load transfer between two feeders.
