While a microgrid is in the on-grid mode, itcan receive energy from the main grid, and the energy storage system should make the longest cycle life as its optimal goal, and choose the appropriate type of energy storage system according to the maximum power and fluctuation of PV/wind power.
However, there are still several issues such as microgrid stability, power and energy management, reliability and power quality that make microgrids implementation challenging. Nevertheless, the energy storage system is proposed as a promising solution to overcome the aforementioned challenges.
Structure of typical microgrid energy management system. A microgrid has two operation modes, namely on-grid and off-grid operation. When a microgrid is detected to be islanding, or it needs to operate independently according to prevailing situation, it should rapidly disconnect from the public grid to switch into the off-grid operation mode.
A microgrid is a single controllable unit composed of distributed generation, energy storage, and load from an aspect of a system. The normal microgrid operation has on-grid and off-grid modes and on/off-grid and off/on-grid switching status. The following paragraphs will analyze the different operation modes from its operating status: 1.
Concerning the storage needs of microgrids, electrochemical technologies seem more adapted to this kind of application. They are competitive and available in the market, as well as having an acceptable degree of cost-effectiveness, good power, and energy densities, and maturity. The modularity of electrochemical technologies is another advantage.
