This paper studies the long-term energy management of a microgrid coordinating hybrid hydrogen-battery energy storage. We develop an approximate semi-empirical hydrogen storage model to accurately capture the power-dependent efficiency of hydrogen storage.
A microgrid will include power generation such as solar panels or wind turbines, a storage element such as batteries to store the renewable energy generated and an intelligent controller. A microgrid is normally connected to the main grid but can be disconnected if necessary (islanded) for example during a power outage.
The probability the BESS stops functioning at a level necessary to support a microgrid that is islanded for less than 2 weeks is very small. The anticipated battery degradation rates for systems is inconsequential over a two-week period and can be ignored.
The battery achieves significant revenue from the frequency regulation market. The breakdown of wholesale revenue is about 60% from frequency regulation, 39% from energy, and less than 1% from spinning reserve. The demand response revenue is reduced compared to the diesel-only microgrid because of the reduced EDGs.
The hybrid microgrid consists of networked diesel generators, PV panels, and battery storage. To calculate the expected performance of the backup system for a given outage, we first determine the initial probabilities of being in each system state, which is dependent on the number of working generators and the battery initial state of charge (SOC).
Remote microgrids are found on islands or in parts of the world that have no main power sources. They are independent and not connected to the grid. Hybrid microgrids use two or more energy sources, for example, solar and wind power, to generate their energy. This energy is then stored in a battery system.
