Multi-energy complementarity and energy storage

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.

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 is multi-energy thermo-chemical complementary technology?

Multi-energy thermo-chemical complementary technology refers to the selection of a suitable endothermic chemical reaction to convert thermal energy into fuel chemical energy, improve energy conversion efficiency, and achieve renewable energy storage and transport. The technology is currently in the basic research stage.

What is multi-energy complementary system optimization control system?

The multi-energy complementary system optimization control system can perform multi-energy complementary and optimal scheduling for various distributed energy systems based on load forecasting, distributed energy generation prediction, electricity price and gas price.

Does China need a multi-energy Complementation system?

Considering the issues of energy supply and environmental protection, clean energy has become the strategic basis for China’s development. So, the multi-energy complementation (MEC) comprehensive energy system has gradually been widely used (Nguyen and Huynh 2019).
