For users, photovoltaic cells, storage devices, and PETs are the users'' inherent assets, i.e. the energy produced by photovoltaic and energy storage devices are essentially free of charge. Therefore, it is of great practical significance to minimise the cost of purchasing power from the grid through the capacity optimisation algorithm.
