Technical FAQs 4

Can multi-energy complementary system with wind-solar-hydrogen coupling improve the economy?

Based on the grid-connected smoothing strategy of wind-solar power generation and the energy management strategy of hybrid energy storage module, the capacity configuration optimization model of multi-energy complementary system with wind-solar-hydrogen coupling is further established to improve the economy of the system.

How can a multi-energy complementary system improve the system control strategy?

To satisfy the requirements of wind-solar power grid connection, and then enhance the system’s stability and economic efficiency, the capacity configuration method of the multi-energy complementary system has been optimized, and thus improved the system control strategy.

How does a hybrid energy storage module satisfy energy conservation constraints?

The dynamic operation of the system satisfies the energy conservation constraint, that is, the difference between the wind-solar complementary output power generation and the grid-connected power is adjusted by the hybrid energy storage module, which can be expressed as Eq. 26: (2) Equipment operation constraints.

How do solar and wind power affect energy storage devices?

Additionally, the fluctuating outputs of solar and wind power impact the frequent start and stop of the electrolyzer in energy storage devices, reducing their lifespan and hydrogen production efficiency.
