Outline of Final Research Achievements |
An energy management system model was developed that takes into account the uncertainties in energy demand and solar insolation predictions, and the activation of the provision of grid flexibility. Numerical simulation results show that electricity prices (incentives) can be adjusted appropriately and that sufficient grid flexibility can be procured from prosumers. The heat pump water heater is widely used in residential dwellings as a hot water supply device, and is expected to be utilized as a low-cost grid flexibility resource in the future. In the verification of the actual system, as in the simulation, it was possible to meet the demand for hot water while coping with the uncertainty of energy demand, demonstrating the effectiveness of the developed control method and system.
