Power system energy management is performed at different levels with different aims. The most important goals of optimal energy management of the power systems are cost reduction, reduce emissions, improve reliability and power quality indexes, increase profitability, etc. Innovative methods can be used to provide an energy management plan, or energy management can be defined as an optimization problem and optimization algorithms can be used to solve it. Uncertainties are also very important issues in power system operation programs, especially in the lower levels of the power system (microgrids). The electric vehicle parking lots or aggregators can also be used in the microgrids to store energy, in which case the issue of energy management takes on a new face. Therefore, to provide a good energy management program for the power system, one must have a detailed knowledge of its components and the technical constraints of the power system. Therefore, to provide a good energy management program, a comprehensive model of the power system with detailed data should be provided.
