Estimating voltage security usage in deregulated electricity markets Conference Paper uri icon


  • This paper presents a procedure, using information from a power flow or a state estimator, to estimate the usage of voltage stability margin by transactions. The proposed methodology applies to a composite power market framework that has both spot market type and bilateral long-term type transactions. The computational procedure estimates the impact of all the transactions on voltage security through a single decomposition. Test case illustrates the results of the procedure. The applicability of this method on existing Energy Management Systems (EMS) that handles real-life system is discussed. 2005 IEEE.
