With PV energy as the main power supply, an integrated complementary power supply system consisting of wind, hydro, thermal and other power sources is added to provide integrated solution of multi-energy complementary with wind, solar, thermal, hydro, energy storage and pumped-storage, and strive to achieve a more reliable, sustainable and stable supply of green power.
Multi-energy complementary systems usually include thermal power (including gas turbine), wind power, solar power (photovoltaic), hydropower, pumped storage and other types of power supply. As a conventional schedulable power source, thermal power can be adjusted to generate a certain peak amplitude, and the output speed is slow.
What are the core modules of a multi-energy complementary system?
For complex multi-energy complementary systems, through the establishment of a system platform for analytical processing and global optimization management, the core modules include forecasting, analysis and decision-making links, grid, renewable energy, non-renewable energy, energy storage systems, and various energy loads.
How many types of solar-based multi-energy complementary systems are there?
This work conducts a comprehensive R&D work review on seven kinds of solar-based multi-energy complementary systems. For different kinds of solar-based hybrid systems, the typical system configurations, solar subsystem types, output products and typical performance parameters are separately summarized.
How can multi-energy hybrid power systems solve the problem of solar energy?
The developments of energy storage and multi-energy complementary technologies can solve this problem of solar energy to a certain degree. The multi-energy hybrid power systems using solar energy can be generally grouped in three categories, which are solar-fossil, solar-renewable and solar-nuclear energy hybrid systems.
Are solar-biomass energy and solar-geothermal energy hybrid systems effective?
Solar-biomass energy and solar-geothermal energy hybrid systems can achieve 100 % renewable energy utilizations. Solar and wind energies can achieve a relatively good complementary relationship in time, and solar-wind energy hybrid systems can effectively solve the problem of power supply in remote areas.
Can solar-based multi-energy complementary systems solve the problems of intermittent and low utilization rate?
However, solar energy still has the problems of intermittent and low utilization rate. Different kinds of solar-based multi-energy complementary systems were proposed to solve these problems. This work conducts a comprehensive R&D work review on seven kinds of solar-based multi-energy complementary systems.
