Description
On-grid microgrids are a kind of local energy network that can work in coordination with the main power grid. It integrates distributed energy microgrid resources such as solar and wind energy (DERs) as well as energy storage systems, and achieves efficient power distribution through advanced microgrid controllers. Unlike off-grid microgrid systems, grid-connected microgrid systems can obtain electricity from the main grid when needed, ensuring the stability and continuity of energy supply.

How On-Grid Microgrid Works?
Grid-connected microgrid systems achieve dynamic balance with the main power grid by intelligently integrating multiple energy components, providing users with stable and efficient power supply. The core lies in integrating renewable energy sources (such as solar photovoltaic panels and wind turbines), energy storage devices (such as lithium-ion batteries or flywheel energy storage), and advanced microgrid controllers to build a flexible energy ecosystem.
Under normal operating conditions, grid-connected microgrids monitor and optimize power distribution in real time through the microgrid control system to ensure the efficient utilization of energy. For example, when the solar power generation is sufficient, the system gives priority to using local renewable energy and stores the excess electricity in energy storage devices or feeds it back to the main power grid. During the night or low power generation periods, the system can seamlessly switch to obtain electricity from the main power grid, ensuring the continuity of power supply. This dynamic balance not only enhances energy utilization efficiency but also significantly reduces users’ electricity bills.
Distributed microgrids demonstrate strong flexibility and resilience during peak electricity consumption or when the main power grid fails. The microgrid controller quickly adjusts energy allocation through intelligent algorithms, prioritizing the use of local energy storage or renewable energy. When necessary, it can switch to “island mode” for independent operation to ensure power supply for critical loads such as hospitals and data centers. Meanwhile, the system adopts grid synchronization and power quality management technologies to maintain stable voltage and frequency and prevent equipment damage caused by power fluctuations.
The microgrid control system, as the “brain”, relies on sensors, communication networks and data analysis to monitor energy production, storage and consumption in real time and optimize dispatching. This intelligent management enables grid-connected microgrids to address complex energy challenges and provide reliable and sustainable power support for residential, commercial and community areas.
Cost and On-Grid Microgrid Installation Guide
The cost of on-grid microgrid systems is influenced by multiple factors, including system scale, component selection, and specific application scenarios. Energy storage capacity is one of the main cost drivers. The type of battery (such as lithium-ion, lead-acid or flow batteries) and capacity size directly affect the investment budget. In addition, the integration degree of renewable energy sources (such as photovoltaic and wind power) will also affect the overall cost. Systems with a high proportion of renewable energy may require more complex energy management systems (EMS). The degree of intelligence of the microgrid controller is equally crucial. Advanced algorithms and predictive functions can enhance efficiency, but they will also increase the initial investment. To ensure the stable operation of the system, installation must be carried out by a professional team. They are not only responsible for equipment deployment but also need to ensure seamless synchronization between the microgrid and the main grid, and comply with local grid norms and safety standards. We offer comprehensive cost assessment and installation guidelines to help customers optimize system configuration.
