2.1. System description The microgrid system powering a municipal office building comprises three key elements: two wind turbines, a water electrolyzer, and an MGT, collectively providing electricity and heat. The wind turbines act as the primary electricity source, with surplus energy directed to the water electrolyzer for hydrogen production.
One infrastructure that embodies this approach is the “microgrid” concept. A microgrid is a power system defined by specific electrical boundaries, equipped with a resource management control system, and possessing generation capacity surpassing critical load .
Conclusions This paper presented the development of a smart management system for a microgrid, featuring two wind turbines as the primary renewable source and an MGT for power regulation. The microgrid incorporated an electrolyzer, enabling power storage with the produced green hydrogen facilitating cleaner MGT operation.
The expense or revenue from buying or selling electricity varies by the hour, referencing data from Ref. . Notably, information from the Norwegian Water Resources and Energy Directorate indicates that the grid typically procures electricity from the microgrid at a rate close to the spot price .
The growing adoption of renewable energy technologies, such as solar panels, wind turbines, and geothermal systems, is increasingly powering and heating buildings, with the microgrid concept being applied to both residential and commercial properties, as reviewed in Table 1.
