A Flexible Resources Planning Method Based on Time-Series Operation Simulation

The connection of high-penetration renewable energy brings severe volatility and uncertainty, which puts forward higher requirements for the flexibility of the power system. At the same time, the problem of matching supply and demand of flexibility has also expanded to a longer time scale, which requires the long-term flexibility resources. However, the existing methods based on typical scenarios may no longer be applicable. And the models with complex time series characteristics also bring challenges to the system. To this end, this paper proposes a flexible resources planning method that considers time-series operation simulation, applying the original operation simulation idea in scheduling to the planning field to accurately consider the adjustment capabilities of different flexible resources in various scenarios of the power system. Finally, an IEEE-9 bus system is used to simulate, and the results verify the effectiveness of the proposed method in improving economy and flexibility.
