To solve the above problems, an auxiliary energy storage system (ESS) has been widely used to provide frequency support with the rapid development of energy storage equipment. In [ 9, 10 ], the authors applied ESS to restrict the frequency excursion caused by an uncertain disturbance in the wind integrated systems.

The elements utilised in cogeneration systems can be classified into three main types; direct energy supply from an upstream grid, converters, and energy storage devices [38]. Converter devices are used to transform the energy or energy carriers to the required form of energy such as gas boilers, heat pumps, and gas turbines.

The term ''grid'' refers to the electrical or utility grid feeding domestic and commercial buildings. An on-grid solar system is directly connected to the electrical grid through an inverter and metering equipment. It cannot supply power at night. An off-grid system does not connect to the grid and charges batteries for night-time use.
