Exploiting the Inherent Flexibility in Transmission Network for Optimal Scheduling, Wind Power Utilization, and Network Congestion Management

Owing to the economic, social, and political problems in expansion of transmission infrastructure, novel topologies are demand efficiently utilize existing infrastructure. On other hand, there is a tremendous increase wind power generation around globe. One main challenges hindering penetration large-scale network congestion due limited capacity. To address these two issues, this study develops co-optimized optimal switching (OTS) dynamic line rating (DLR) model optimize system resources by mitigating maximizing accommodation. This new concept exploiting inherent flexibility named as flexible (FTDLR), which deploys OTS coordination with DLR control tool assets. A two-stage stochastic unit commitment framework used deploy proposed FTDLR model, dynamically capacity based on meteorological parameters at same time optimally select candidate lines be switched off from network. comprehensive analysis performed characterize performance operation cost, congestion, curtailment. The further tested part contingency where both generator failure outages considered. Test results IEEE 24-bus demonstrate that using FTDLR, service operator could substantially reduce dispatch improve accommodation, relieve congestion. scalability feasibility optimization problem validated larger 118-bus system.
