Multi-Flexibility Resources Planning for Power System Considering Carbon Trading

Clean and low-carbon energy represented by wind power photovoltaic will develop rapidly form a new system with high proportion of renewable energy. In the context economy, how to make reasonable planning for flexibility resources is crucial development systems. this paper, we establish multi-flexibility resource model based on low carbon economy considering “source–load–storage”. First, ladder-type trading cost accounting proposed, set evaluation indexes are proposed. Then, objective minimizing sum operation cost, investment system, established constraints such as balance constraint, consumption constraint. Finally, proposed in paper validated IEEE-RTS96 system; results show that: (1) collaborative source–load–storage multi-flexible can obtain best overall economics, although increases USD 12.6M, total reduced 11.22% due reduction coal generation curtailment penalty cost; (2) penetration grows, demand storage gradually increasing; when installed capacity grew from 800 MW 1600 MW, thermal decreased 53.5% increased 200%; (3) decreases 1.35% compared without trading, 2.5% traditional but its emissions decrease 5.5%.
