The authors study an independent grid where the penetration of wind energy is high and exploit the joint planning of energy storage and a renewable energy source, as it can potentially result in a more economical and efficient energy system. More specifically, they consider an energy system that consists of a gas‐fired plant, and a small wind farm with a capacity for energy storage. They assume that the gas‐fired plant has a maximum generation capacity that is no more than the electricity demand. They first propose an optimisation model with known wind speed and electricity demand. Then they gradually extend this deterministic model to take into account the stochastic nature of the renewable energy source and electricity demand. Furthermore, they consider the possibility of connecting their system to the National Grid, which they import from or export to when their system has an energy shortage or surplus in meeting the demand. Their results provide helpful insights in planning the joint deployment of generation capacity and energy storage, and show that the system operates more efficiently and economically when it is connected to the National Grid.
