In conventional power systems, client-server architecture and centralized control are adopted for data acquisition and supervisory control, and the speed of message transmission and the fault responses is slow. In contrast, various types of distributed energy resources (DERs) with different characteristics and of different capacities exist in a microgrid system, and client-server architecture and...
A microgrid consists of many small scale distributed energy resources, energy storage devices, loads and communication links. It customarily operates in the grid interconnected mode but is also capable of operating in an islanded mode. With the growing demand of clean energy power generation, the renewable energy generation systems mainly solar, wind and fuel cells are slowly appearing within the...
Electrical distribution systems (EDS) are undergoing some significant changes at various scales and levels. These changes are triggered by several factors such as the event of distributed energy resources (DER) and the need to improve the quality of supply while achieving economical optima. Hence, several research initiatives, technological development and experiments have been launched worldwide...
This paper presents a method for calculating the reliability of distribution systems with distributed energy resources (DER). The impact of intentional islanding of the DER units on the reliability is studied in detail as well as the impact of different switching devices. A Monte-Carlo-based computer program has been developed to simulate the performance of different typical distribution feeders....
