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 …
Microgrid (MG) is a modern and alternative solution of present deregulated power scenario to provide distributed generations in low voltage network.
