Summary
Conventional centralized power systems have faced different problems such as depletion of fossil fuel resources, environmental pollution, and poor energy efficiency. To cope with these problems, efforts have been made in discovering solutions that can help transform the electric power system from its centralized form of operation to a more interactive distributed model. The new concept of generating power locally at distribution voltage level has been developed by using distributed energy resources like natural gas, biogas, wind, solar photovoltaics, fuel cells, combined heat and power (CHP) systems, microturbines, and Stirling engines and their integration into the grid. Microgrids can help integrate distributed energy resources and storage units into the power system, increasing its efficiency and resilience to natural and disruptive events.
Following the concept of microgrids, nanogrids have been developed for integration of distributed energy resources in low-voltage systems. The structure of a nanogrid is similar to a microgrid, but it is designed for a much smaller geographic area and entails a smaller capacity. Nanogrids are designed to satisfy specific objectives within a microgrid such as the surgery building within a hospital or the police station within a university campus.
Microgrids and nanogrids have different advantages, but planning and operation of these systems have faced several challenges. Therefore, advanced solutions and techniques are required to be developed to increase their efficiency, reliability, and resiliency.
The topics for this special issue include, but are not limited to the following:
• AC/DC and hybrid microgrids and nanogrids
