Wind Solar and Storage Microgrid Design

Can DFIG control a wind–solar storage hybrid ac–dc microgrid?

On this basis, this paper presents an improved model of a wind–solar storage hybrid AC–DC microgrid based on a doubly-fed induction generator (DFIG), along with control methods for smooth transitions between the grid-connected and islanded states, ensuring transient and steady-state stability. The structure of this paper is as follows.

How does a microgrid maintain a power balance?

The power balance is maintained by an energy management system for the variations of renewable energy power generation and also for the load demand variations. This microgrid operates in standalone mode and provides a testing platform for different control algorithms, energy management systems and test conditions.

How can a microgrid improve the reliability of solar PV?

In order to overcome the problems associated with the intermittency of solar PV and enhance the reliability, energy storage systems like batteries and/or backup systems like diesel generators are commonly included in the microgrids [11, 12].

Is a microgrid a small controllable power system?

Although there are different views of a microgrid in terms of capacity, from tens of kilowatts ( k W) to a few megawatts ( M W ), this study considers a microgrid as a small controllable power system whose nominal power output is 10 k W. Several studies have been done on the modeling of hybrid PV-wind energy systems.

Can microgrids improve energy resiliency?

(Marqusee, Schultz, & Robyn, 2017) Microgrids can enhance energy resiliency by providing energy surety (i.e., loads have certain access to energy) and survivability (i.e., energy is resilient and durable in the face of potential damage).

What is microgrid management system?

microgrid management system is an integrated real-time power distribution management system unifying SCADA functions, energy resource controls, and load management, with a common user interface.
