Energies | Free Full-Text | Stochastic Optimization of Microgrid
The optimized operation cost of a microgrid in different cases is shown in Table 3. In case 1, case 2, and case 3, the optimized operation cost of a microgrid is $ 386.29, $ 370.19, and $ 382.08, respectively. The difference of costs in the three cases shows that the demand response program and the cost of the demand response will …
Microgrids: What Are They and How Do They Work? | EnergySage
The electrical grid exists to supply our electricity demand, ensuring the two are balanced and connecting electrical supply to electrical demand with the transmission and distribution system. In practice, a microgrid works in the exact same way, just for a smaller geographic area, like a couple of buildings or a local community.
