Microgrid
Microgrid. A microgrid is a local electrical grid with defined electrical boundaries, acting as a single and controllable entity. [1] It is able to operate in grid-connected and in island mode. [2] [3] A '' stand-alone microgrid '' or '' isolated microgrid '' only operates off-the-grid and cannot be connected to a wider electric power system. [4]
Economic Optimal Scheduling of Microgrid Based on Improved …
The microgrid is an important means for distributed power supply to connect to the power grid operation. However, the volatility and randomness of distributed power supply will result in the incomplete absorption of renewable energy, which in turn reduces the operation economy of power grid. To address this problem, taking the minimum of the total cost of …
