How can interconnection planning improve the reliability and economic operation of microgrids?

The interconnection planning will enhance the reliability and the economic operation of a community of microgrids. The proposed approach will apply a probabilistic minimal cut-set-based iterative methodology for the optimal planning of interconnection among microgrids with variable renewable energy sources.

What is a grid-connected microgrid?

Grid-connected microgrids are largely adopted to support the integration of DG units and, in particular, of renewable energy sources (RES) in distribution networks .

Why is microgrid important in Smart Grid development?

Microgrid is an important and necessary component of smart grid development. It is a small-scale power system with distributed energy resources. To realize the distributed generation potential, adopting a system where the associated loads and generation are considered as a subsystem or a microgrid is essential.

What is a microgrid planning capability?

Planning capability that supports the ability to model and design new microgrid protection schemes that are more robust to changing conditions such as load types, inverter-based resources, and networked microgrids.

What is a microgrid and how does it work?

A microgrid is a group of interconnected loads and distributed energy resources within clearly defined electrical boundaries that acts as a single controllable entity with respect to the grid.2 A microgrid can operate in either grid-connected or in island mode, including entirely of-grid applications. Figure 1 shows one example of a 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.
