Microgrid Stability Issues and PI Control Technique

Microgrid encourages use of renewable energy resources like photo voltaic (PV), wind etc. which reduces pollution. The type of microgrid system and the control method will get vary according to the application of microgrid which will affect the microgrid stability. Here we have discussed the stability issues of different types of microgrid. These issues depend on the operation mode, control method, different small resources used in microgrid. There are types of control techniques for voltage and frequency control. The major novelty of system lies within the coordination between individual with proportional and integral (PI)controller.
