Abstract
A new solar cold storage system is proposed for solar photovoltaic power generation technology, demand side management（DSM） and thermal energy storage technology. The aim is to explore the potential of using cold energy storage and off-grid solar photovoltaic power generation to reduce and transfer peak power demand and reduce power consumption costs. The Simulink simulation model of the system is established and further revised by experiments. The results show that the energy saving rate of the new system can reach 48.38% in May-August, while the corresponding electricity bill can save up to 65.40%. Overall, the system can achieve more than 60% of electricity cost savings in May-August.
