Comparative Analysis of Different Types of Micro-grid Architectures and Controls

An innovative and smart micro-grid model is an essential for the integration of distributed energy resources into the electrical power distribution network. There are various types of micro-grid architectures that have been designed and implemented in the last few years. These micro-grid architectures have their key advantages and limitations. This paper has been prepared with the objective to identify and address, key challenges and solutions for integration of micro-grid into the distribution network. It reviews different micro-grid architectures and control strategies which can help to address various challenges i.e. voltage imbalance, power quality, demand side management, smooth islanding operation of a micro-grid.
