Mikroravinteet, also known as microgrids, are localized grouping of electricity sources and loads that normally operate connected to and synchronous with the traditional wide area synchronous grid (WASG), but can also be adapted to operate as an independent system. They are designed to improve the reliability, efficiency, and sustainability of the electricity supply. Microgrids can include a variety of distributed energy resources (DERs) such as solar panels, wind turbines, combined heat and power (CHP) systems, energy storage systems, and demand response programs.

The primary goal of a microgrid is to provide a more resilient and efficient power supply, especially in areas prone to frequent outages or natural disasters. During grid outages, a microgrid can continue to operate independently, ensuring critical services such as hospitals, water treatment facilities, and communication networks remain operational. Microgrids can also help integrate renewable energy sources, reducing reliance on fossil fuels and lowering greenhouse gas emissions.

There are two main types of microgrids: grid-tied and off-grid. Grid-tied microgrids are connected to the main power grid and can exchange power with it. Off-grid microgrids operate independently and are typically used in remote or rural areas where grid connection is not feasible. Microgrids can be small, serving a single building or a small community, or large, powering an entire neighborhood or city.

The implementation of microgrids requires careful planning and coordination among various stakeholders, including utility companies, local governments, and private sector entities. Challenges include technical issues related to stability and synchronization, as well as economic and regulatory barriers. However, with advancements in technology and increasing awareness of the benefits of microgrids, their adoption is growing worldwide.
