Abstract: The increasing presence of distributed generation and the steady modernization of power distribution system equipment have presented new opportunities in power distribution system studies. This thesis will focus on the impacts new equipment technology and regulatory changes, such as the move to performance based rates, have on distribution protection system design. Specifically, this thesis addresses three aspects in the design of protection systems. First, to determine new protection device locations, switch placement schemes are proposed which allow systems with DGs to intentionally island in fault scenarios. Second, network equivalent models are proposed to improve the accuracy of short circuit analysis. These techniques are used to size protection devices and to determine protection device settings. Finally, to address distribution protection system design and coordination, a multi-agent based adaptive protection system is proposed. Extensive simulation tests on a 20-bus system and a 394-bus system with single/multiple DGs yield promising results.
