Chapter 1 Solar Electric System Fundamentals

What is a multi-energy complementary system?

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.
