Abstract

The invention relates to a comprehensive energy supply system based on solar frequency division utilization. The system comprises a solar frequency division utilization-concentrating photovoltaic photo-thermal module which is configured to receive solar energy and generate electric energy and heat energy through the frequency division utilization of the solar energy; an organic Rankine cycle module which is configured to receive the heat energy generated by the solar frequency division utilization-concentrating photovoltaic photo-thermal module and convert the heat energy into electric energy; a fuel cell-electrolytic tank integrated module which is configured to convert redundant electric energy into chemical energy for storage through an electrolytic tank under the condition of strong solar radiation, and convert the chemical energy into electric energy through a fuel cell under the condition of weak solar radiation; and a current modulation module which is configured to modulate the generated electric energy, complete conversion between alternating current and direct current, and realize electric energy distribution to a power grid. The solar energy comprehensive utilization rate is increased, the energy storage function is achieved, solar energy fluctuation is stabilized, peak clipping and valley filling are achieved, meanwhile, high-added-value products can be obtained, and an electricity and hydrogen double-supply comprehensive energy supply system is formed.

Description

technical field [0001] The invention relates to a photoelectric-photothermal driven organic Rankine cycle-proton exchange membrane fuel cell / electrolytic cell comprehensive energy supply system based on solar frequency division utilization, and relates to the technical field of solar energy. Background technique [0002] Renewable energy has experienced strong growth for more than ten years, its capacity has increased rapidly, its cost has fallen sharply, and its substitution has been continuously strengthened. The trend of becoming the main energy source has gradually become clear, and energy transformation has become increasingly urgent. Due to the randomness, intermittence and volatility of wind and light-based new energy, large-scale access to the power grid will bring severe challenges to the operation of the power grid. The new power energy storage technology can bring power and energy buffer to the power network and even the overall energy network, which can solve ene...
