Stochastic Optimal Operation of Low-Carbon Renewable Energy System

This paper proposes a low-carbon renewable energy system for coupled multi-energy supplies. In this system, various energy conversion and storage devices are adopted to convert and condition the biomass-solar-wind hybrid renewables into different forms of energy carriers. Carbon dioxide emissions incurred during the energy conversion process is captured based on the power-to-gas technology for subsequent cyclic utilization. A multi-energy scheduling scheme is then developed to optimize the coupled electricity, gas, heat, and carbon dioxide flows for energy-efficient conversion and storage. Case studies are presented to demonstrate the superiority of the proposed low-carbon system in the improvement of renewable accommodation and energy efficiency.
