Benefit at Grid Level by Using DoS Actions via Combined Photovoltaic and Solar Panel System

Abstract

A systematic evaluation of the potential energy saving and CO2 emissions reduction on buildings and neighbours has been carried out, when a renewable energy system is locally installed. The exploitation of a combined solar and photovoltaic system and the integration of suitable energy management actions were deeply investigated. Saving up to 40% on the energy consumptions at house level and savings up to 10% on wiring losses in the electric chain seem to be easily obtainable. This produces savings at national grid level by applying energy management in a large number of houses and buildings. The results here pointed out suggest the possibility of postponing the strengthening of power grids. The consequent economic relevant benefit could persuade economic lobbies about the importance of energy management through connected household appliances. In the paper a grid simulator has been defined with the specific inputs and parameters to model the distribution system, both at low and medium voltage level of the electric system. In the grid simulator the HV/MV transformers, the MV/LV transformers, the LV feeders, the MV feeders, the LV derivations have been considered. Results at neighbour and country level are very suitable and verify the relevant role of the CPS in the whole electric chain.
