Wind/PV/CSP Thermal Storage Hybrid Power Plant Overview
The wind/PV/CSP hybrid power plant comprises of a CSP power plant, PV power plant and wind power plant. If needed, an electric heater can be installed to store the curtailed PV or wind power into the MSES system. By optimizing the generation mode of the plants and through the storage system, the CSP power plant will provide peaking or frequency regulation services to the grid in addition to ensure a continuous and stable electrical output.
Operational Mode
In the operation of wind/PV/CSP hybrid power plant, CSP generator set provides low-carbon peak power and long-term energy storage services.
When PV or wind power is at its peak production, CSP power stops generating electricity or runs at a low load and only charge storage. When PV or wind power output runs low or stops, the MSES system of CSP starts to operate full load to generate electricity to satisfy the peak demand.
In addition, the MSES system can be used to store curtailed energy from PV or wind to make full use of the renewable energy. Wind/PV/CSP can work jointly as a whole system to provide power.
Advantages
Zero Fossil Energy Consumption
Fit with Natural Resource Conditions
Absorbing a Large Amount of Abandoned Electricity
Provide High Quality Heat Energy
Compared with the wind power that needs natural gas or coal power as a balancer, the wind/PV/CSP hybrid solution use CSP which completely gets rid of fossil energy and truly emit zero carbon.
In China, areas rich in scenic resources often have low rainfall and flooding water resources, so it is difficult to build hydropower or pumped storage to form multi-energy complementary scenic water storage. Because of the good lighting conditions, it is very suitable for the construction of photothermal power generation; In addition, in the wind-solar thermal storage multi-energy complementary power plant, the geographical distance of wind power, photovoltaic, energy storage type CSP generator set is close, which facilitates the integration of power grid scheduling.
The wind-solar thermal storage multi-energy complementary power plant can realize the power abandonment and absorption function that other multi-energy complementary schemes cannot achieve. By configuring the molten salt electric heater, the abandoned electricity of wind power and photovoltaic can be stored in the molten salt energy storage system in large quantities, and then the electricity demand can be met by the photothermal turbine power generation system when needed.
CSP is configured with large capacity MSES, so it can provide high-quality heat energy for the surrounding thermal users while providing electricity.
