Planning of Renewable Energy Bases in Desert Areas Considering the Response Characteristics of Compressed Carbon Dioxide Energy Storage
摘要
The inherent anti peak characteristics from renewable energy resources may cause uncertainty in the output of thermal power units and in its own consumption, affecting the economic operation and power supply reliability of the whole power system. To ensure the reasonable consumption of renewable energy such as wind and photovoltaic, firstly, this paper introduces to construct a compressed carbon dioxide energy storage (CCES) model according to the constraints of traditonal power systems, and sets evaluation indicators to analyze the characteristics of the CCES. Then, based on the situation of renewable energy base in desert areas, taking into account the minimum operating costs of thermal power units, CCES, wind and photovoltaic power as the objective function, which arranges the charging and discharging power of energy storage systems and the power of thermal power units. Finally, simulation analysis is conducted on the selected data, which confirms the effectiveness and feasibility of the model constructed.
