Regional Microgrids

Evolution of the concept of microgrids to enable Sufficient Electricity, Uninterrupted Power, Green Electricity and environmental-friendly interaction across Australia. 

• Islands, remote mountainous areas, isolated villages – Having Power

• Hospitals, factories, military, commercial buildings – Reliable Power Supply

• Wind, light, storage – Green Energy + Reliable Power Supply

• Diverse integration and Supply-demand interaction – Supply-demand shift Prosumer + Service + Market Mechanism

​

Definition of Microgrid:

• A microgrid refers to a small-scale power generation and distribution system composed of distributed power sources, power loads, distribution facilities, monitoring, and protection devices (including energy storage devices when necessary). Microgrids are divided into grid-connected microgrids and standalone microgrids, capable of self-control and quality management. (Characteristics: Miniature, Clean, Autonomous, Friendly)

• Microgrids are divided into grid-connected microgrids and standalone microgrids. They can achieve self-control and autonomous management. The grid-connected microgrid can operate connected to or independently from the external grid; the standalone microgrid is not connected to the external grid and balances its own electricity.

• The microgrid, as an important support for the "Internet" smart energy and a technological means for friendly interaction with the large power grid, can enhance the safety and reliability of the power system, promote the introduction and local consumption of clean energy, improve energy efficiency, play a significant role in energy conservation and emissions reduction, and is conducive to building a conservation-oriented society. To promote the orderly and healthy development of the electric power industry, advance power system reforms, further standardise microgrid construction and operation management, and gradually establish a diversified, supply-demand interactive, efficiently allocated energy production and consumption system, these methods are specially formulated.

Key Elements and Technical Points of Microgrid

• Resisting risk and ensuring supply capability during disasters: safety and flexibility of protection control in on-grid and off-grid operation and switching modes, addressing the power reliability risks of extreme disasters (isolating power source -> isolating microgrid)

• Relieving the pressure on main grid construction and operation: safety and economic constraints of the grid, guiding optimized microgrid operations.

• Guiding the orderly construction of distributed power sources: prioritize the grid and its specifications (Grid Code), addressing non-grid main body construction patterns.

• Helping to enhance the consumption capacity of new energy: optimizing local energy structure and energy services based on market-oriented methods.

• Optimizing the profit model of non-grid entities: innovating market mechanisms and business models between the grid and operators, operators and users, promoting the sustainable development of the microgrid model.
