Summary This paper investigates the effect of using a proposed supercapacitor‐based mitigation method to mitigate switching overvoltages (SOVs) on a microgrid system. At first, the effectiveness of the new proposed supercapacitor‐based mitigation method performance is evaluated. Then, a comparison between a traditional SOV mitigation method, such as surge arrester, and the proposed supercapacitor mitigation method is studied. SOVs result due to unsymmetrical switching operation during de‐energization procedures. The μG 2 operational modes, grid‐connected mode and isolated mode, are taken into consideration in this study. A small hydro generation unit and 3 variable speed, doubly fed induction generator‐based wind turbines are the main renewable power generation units in the investigated microgrid system. Alternating transient program is used in this study for simulating of the investigated microgrid.

“…Electricity market deregulation, environmental concerns, technology advancement, and an increased trend for reducing the dependency on fossil fuel are the main causes to integrate distributed generation (DG) units into the distribution power network [1,2]. Generally, DGs have a diverse generation capacity, availability, and primary energy sources.…”

This chapter presents the reliability evaluation of a microgrid system considering the intermittency effect of renewable energy sources such as wind. One of the main objectives of constructing a microgrid system is to ensure reliable power supply to loads in the microgrid. Therefore, it is essential to evaluate the reliability of power generation of the microgrid under various uncertainties. This is due to the stochastically varying wind speed and change in microgrid operational modes which are the major factors to influence the generating capacity of the individual generating unit in the microgrid. Reliability models of various subsystems of a 3-MW wind generation system are developed. The impact of stochastically varying wind speed to generate power by the wind turbine system is accounted in developing subsystem reliability model. A microgrid system reliability (MSR) model is developed by integrating the reliability models of wind turbine systems using the system reliability concept. A Monte Carlo simulation technique is utilized to implement the developed reliability models of wind generation and microgrid systems in a Matlab environment. The investigation reveals that maximizing the use of wind generation systems and storage units increases the reliability of power generation of the proposed microgrid system in different operating modes.
