Microgrids have the potential to provide customers with clean, low-cost, and most critically, resilient power. SEPA hosted a briefing for Microgrid Controller Standards IEEE 2030.7© and IEEE 2030.8© to provide an overview of the standards and explore the challenges and next steps for microgrid standards.
Thus, many international microgrid standards are still being developed, several standards are on-going drafting by IEEE and IEC organization, such as self-regulation of dispatchable loads, monitoring and control systems, energy management systems and use case design.
Why do we need a standard system for microgrids and distributed energy resources?
The prosperity of microgrids and distributed energy resources (DER) promotes the standardization of multiple technologies. A sound and applicable standard system will facilitate the development of renewable energy and provide great guiding significance for technology globalization.

Overview: State Grid Corporation of China is the world's largest utility enterprise, covering 88 percent of China's land area and serving over 1.1 billion people. It maintains the longest global safety record for ultra-large power grids and leads in transmission capacity and renewable energy integration.
How much money does State Grid Corporation of China make?
State Grid Corporation of China (State Grid) ranks second with revenue of USD 386.618 billion, one place higher than its ranking in 2020. It tops the list among China's companies.
SGCC accounts for 80% of the Chinese grid, with China Southern Power Grid accounting for the other 20%. : 40 At its creation, SGCC company had a generation capacity of 6.47 gigawatts. In 2003 and progressively so through the early 2000s, electrical shortages caused the government to institute rolling blackouts.
How is China's Smart Grid different from the United States?
China's smart grid efforts are different from those in the United States in that its plans heavily use ultra high voltage (UHV) lines. Several UHV construction projects began in 2012 to bring UHV power lines across Huainan, Wannan, and Shanghai and another from Xilingol League to Nanjing.
