Energy storage (ES) is a form of media that store some form of energy to be used at a later time. In traditional power system, ES play a relatively minor role, but as the intermittent renewable energy (RE) resources or distributed generators and advanced technologies integrate into the power grid, storage becomes the key enabler of low

Electric vehicle (EV) charging stations have experienced rapid growth, whose impacts on the power grid have become non-negligible. Though charging stations can install energy storage to reduce their impacts on the grid, the conventional "one charging station, one energy storage" method may be uneconomical due to the high upfront cost of energy
Environmental Impacts of Centralized Generation. The environmental impacts of electricity generation can contribute to large-scale regional environmental concerns as well as localized concerns that affect the area directly surrounding a power plant. Some impacts vary based on the energy resource—for example, whether the

2. Microgrid decentralized control. With the growth and development of the systems, naturally, centralized control does not give a suitable answer, nor is it sometimes even implementable. In a control system, if the number of data (sensors) and the number of operators increases, its efficiency decreases.
