What is the definition of a green microgrid
The Microgrid Exchange Group defines a microgrid as "a group of interconnected loads and distributed energy resources within clearly defined electrical boundaries that acts as a single controllable entity with respect to the grid. A microgrid can connect and disconnect from the grid to enable it to operate in both grid-connected or island-mode."Read More Download PDF
DC microgrid bus voltage fluctuation
This study proposes an integrated control method for the bus voltage of the DC microgrid to solve the abovementioned problems. As a result, DC bus voltage suffers from rapid changes, oscillations, large excursions during load disturbances, and fluctuations in renewable energy output. Energy storage devices can provide equivalent inertia. To enhance the inertia and response speed of the DC bus interface converter, this paper proposes a power allocation. . Aiming at the problem of bus voltage control in DC microgrid, a dynamic compensation control strat-egy based on a residual generator is designed to complete the voltage compensation of DC-DC con-verter.Read More Download PDF
