It is understood that Shandong Power Grid is a power grid based on thermal power, with large peaks and valleys in electricity consumption, and the main countermeasures for the start-up, shutdown, and adjustment of thermal power units are the key to coordinating and optimizing power generation companies' power generation plans. In order to reduce the losses caused by start-stops, Shandong Power Grid developed and applied a time-series progressive coordination optimization power system scheduling decision technology in 2007. Relying on this technology, in 2010, the unit peaked and stopped 76 times, which was 266 units less than in the same period of 2009. In 2010, the unit was stopped and set aside and stopped 484 times, 188 times less than the same period of 2009. Since 2007, a total of 620 million yuan in economic benefits have been achieved, saving 613,000 tons of standard coal and reducing 5,964 tons of sulfur dioxide emissions.
Solar Battery Pack refers to the overall unit formed by combining multiple solar battery monomers. It is one of the core components of the energy storage system, which is used to store the electric energy generated by solar power generation and supply electricity to electric equipment when needed.
Main effect:
Energy storage: Solar Battery Pack is used to store electricity generated by solar power, and store excess electricity to supply electricity when solar energy is unavailable or power demand exceeds solar energy generation.
Regulating power fluctuations: The output of solar panels is affected by factors such as solar radiation, causing fluctuations in power. The Solar Battery Pack smooths out power fluctuations and maintains steady power output.
Improve self-sufficiency: By storing solar power, Solar Battery Pack can increase the self-sufficiency of the solar system, that is, it can meet the power needs of electrical equipment and reduce dependence on the grid.
Differences from Solar Energy Storage System:
The Solar Battery Pack is an integral part of the Solar Energy Storage System. Solar Energy Storage System is a broader concept that includes all systems used to store solar energy or other energy, of which the Solar Battery Pack is a component.
The Solar Energy Storage System also includes other components such as inverters, charge, and discharge controllers, battery management systems, etc., which together form a complete energy storage system. The Solar Battery Pack is mainly responsible for the function of storing electrical energy. Therefore, Solar Energy Storage System covers more components and functions, and Solar Battery Pack is only one component of it.
