Abstract:
Controlling the frequency and voltage of the power network with renewable energy resources is one of the most important things in the integrity of the network. Therefore, after occurring any accident or fault in the network, the frequency and voltage and in general all the basic parameters of the network must return to their acceptable range within a certain period of time. Despite all the technical, economic and environmental advantages that renewable energy resources have, the presence of these kind of sources may have negative effects on voltage profiles and protection coordination in distribution networks, it is also possible that a part of the network acts as an unwanted island, which complicates the operation and control of the network and creates a risk of electrocution for the network personnel. Therefore, islanding detection is very important and necessary in network protection and load shedding methods are usually used to eliminate this event. In this paper, a multi-objective load shedding method in microgrids is proposed for the frequency stability and reduction of power outages. Among the advantages of the proposed method can be mentioned its flexibility, speed of operation and high accuracy. The proposed method is applied and simulated on a microgrid in the DIgSILENT software environment, and the results of the simulation confirm the advantages of the proposed method.
