6 FAQs about [Microgrid Grid-connected Dispatching Operation Specifications]

What is the optimal dispatch model of microgrid?

This paper constructs an optimal dispatch model of microgrid. The microgrid includes PV, WT, DE, MT and EV. In order to compare with the proposed model containing EVs, a scheduling scenario of optimal dispatch of microgrid without EVs is considered, the two kinds of scheduling scenarios are as follows.

What is the optimization dispatch method of microgrid?

According to the optimization method, the optimization dispatch method of microgrid can be divided into deterministic method and uncertainty method. The deterministic method takes the predicted value of renewable distributed power as an accurate known quantity and then optimizes the dispatch of the microgrid.

Do EVs affect the optimal load dispatch of microgrid?

The structure of micro grid has changed due to the large-scale access of EVs. Therefore, the study of the influence of EVs on the optimal load dispatch of microgrid is of great practical significance. This paper constructs an optimal dispatch model of microgrid. The microgrid includes PV, WT, DE, MT and EV.

What is a microgrid?

The microgrid includes PV, WT, DE, MT. The system is running in grid-connected mode. There is no EV to participate in the dispatch of microgrid. PV and WT also adopt MPPT mode to output power. Other simulation data are same as scheduling scenario 1.

What happens when a microgrid is connected to the grid?

When the microgrid is connected to the grid, there is an electrical interaction between the microgrid and the main grid. When the distributed power output in the microgrid is insufficient, the microgrid can purchase electricity from the main grid to meet the needs of the microgrid.

What are microgrid control objectives?

The microgrid control objectives consist of: (a) independent active and reactive power control, (b) correction of voltage sag and system imbalances, and (c) fulfilling the grid's load dynamics requirements. In assuring proper operation, power systems require proper control strategies.
