After 2030, with the reduction of conventional energy resources, the proportion of fossil fuel electricity will inevitably decline year by year, and the role of the backbone power grid will gradually weaken, and the micro-grid (Micro-Grid) supported by multiple energy sources will have rapid development
.
This microgrid system can be composed of hydropower, photovoltaic, wind power, gas/oil power generation, energy storage and other energy sources, the proportion of various energy sources, the continuity of energy supply is much better than simple photovoltaic power generation and simple wind power generation, so only relatively little energy storage is needed to ensure that the microgrid can be stable, continuous and reliable power supply
.
Since energy storage belongs to local peak shaving, the scale can be small, which saves economic costs and reduces technical difficulty
compared to large-scale energy storage.
When renewable energy becomes the dominant energy source, the microgrid system will be greatly developed, and its main technical features are: a variety of power generation modes are networked operation, with energy storage units and adjustable loads
.
The microgrid power generation system can be divided into microgrids that operate in connection with the large grid and microgrids
that operate independently.
For independent microgrids, the focus is on ensuring the continuous, stable and reliable operation of microgrids, and communication, control and supply and demand balance within microgrids are the focus; For microgrid systems that operate on the grid with the large grid, the main purpose is to make the grid absorb as much renewable energy as
possible.
Since the microgrid system does not rely on the main power grid, but is used in place for on-site power generation, and the excess part is sent to the power grid, its development space will no longer be limited by the power grid transmission capacity
.
The development of networked microgrids is inseparable from smart grids, which can be said to be part of smart grids, and microgrids and distributed generation will change the current grid structure and become a very important part
of the future grid structure.
China's energy grid has long paid attention to the development and construction of distributed energy resources, and microgrids will develop
rapidly in the next 5-10 years.
Regarding the development and construction of microgrids, China Energy Network will discuss
with many energy companies at the most influential China Distributed Energy International Forum 2014 this year.
