Economical Dispatching Strategy of Multi-Energy Coupling Energy System of Offshore Island Considering Concentrating Solar Power Plant

The increasing load of electricity, water, cold, gas, and heat on offshore islands brings certain pressure to the island microgrid. Based on offshore islands, this paper proposes a multi-energy coupling energy system for offshore islands that takes into account solar thermal power stations. The objective function is to minimize the cost of energy purchased by islands within 24 hours, and establish a day-ahead economic dispatch model for offshore islands. Finally, through simulation verification of two types of models, it is concluded that considering the multi-energy coupling system of CSP stations reduces the total cost of purchasing energy for islands, and at the same time increases the consumption of renewable energy in offshore islands.
