The auton- omous operation is one of the features of microgrid. Distributed renewable energy resources and small-scale clean energy generating units are the major generation resources in microgrids. The development of microgrids and distributed clean energy generations will be one of the solutions to carbon emissions and global warming.

Microgrid is an effective means to integrate distributed generation (DG) resource. However, uncertain renewable DG such as wind turbine and photovoltaic outputs and load demands can introduce tremendous difficulties for energy management in microgrids. To mitigate such difficulties, price-based demand response (PBDR) can

Abstract. In the last decade the microgrid (MG) has been introduced for better managing the power network. The MG is a small power network with some energy sources such as distributed generations (DGs). The place and capacity of distributed energy units have a positive impact on the efficiency of the MG. For this reason,

Distributed Generation (DG) refers to the generation of electricity from various small-scale sources of energy such as solar panels, wind turbines, or micro-turbines, located near the consumers

Microgrids offer the ability to integrate a wide variety of generation sources and provide a backbone for future development over time. Energy Plant Operations Proactive management of energy infrastructure is critical to managing carbon footprint, minimizing risk, and extracting maximum efficiencies from utility systems.
