Impact of natural gas system on short-term scheduling with volatile renewable energy

In this paper, the impact of natural gas system on the short-term scheduling with high penetration of renewable energy is illustrated and analyzed. The natural gas infrastructure constraints are integrated into the security-constrained unit commitment model, which minimizes the expected operation cost while considering the variable wind power generation. Benders decomposition is applied to solve the problem with non-linear natural gas network constraints. Illustrative examples demonstrate the effectiveness of the proposed approach for analyzing the impact natural gas system on system scheduling with volatile renewable energy.
