The Microgrid Exchange Group defines a microgrid as ‘‘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. A microgrid can connect and disconnect from the grid to enable it to operate in both grid-connected or island-mode.’’ [pdf]
[FAQS about Microgrid or low voltage grid ]
DSTATCOM is a device that is capable of mitigating multiple power quality issues. It absorbs or injects reactive power into the distribution system and thereby regulates the voltage at the load end. A DSTATCOM consists of Voltage Source Inverter, coupling inductor or an optional transformer, ripple filter and DC link. .
The Dynamic Voltage Restorer (DVR) is a PQ solution which protects the sensitive loads against voltage fluctuations in the grid. The DVR can inject series voltage in phase or quadrature with the source current and hence control. .
The control algorithm of the DVR senses the source voltage, decides the reference load voltage and calculates the voltage to be injected in series. Figure 30.12 shows the scheme for compensation of imbalance in source. [pdf]
