DC AND AC MICROGRIDS FOR STANDALONE APPLICATIONS

Microgrids in power systems
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]

Where are microgrids mainly used
Architectures are needed to manage the flow of energy from different types of sources into the electrical grid. Thus, the microgrid can be classified into three topologies: Power sources with AC output are interfaced to AC bus through AC/AC converter which will transform the AC variable frequency and voltage to AC waveform with another frequency at another voltage. Whilst power sources with DC output use DC/AC converters for the connectio. [pdf][FAQS about Where are microgrids mainly used ]

What are the main functions of microgrids
A microgrid presents various types of generation sources that feed electricity, heating, and cooling to the user. These sources are divided into two major groups – thermal energy sources (e.g.,. natural gas or generators or ) and renewable generation sources (e.g. wind turbines and solar).

Grid-connected photovoltaic inverter AC overvoltage
When the on grid inverter is detected that the grid voltage (AC voltage) exceeds the specified range, the on grid inverters must be turned off and stop working in order to ensure the safety of equi. [pdf][FAQS about Grid-connected photovoltaic inverter AC overvoltage]
