Variable generation dispatch and load distribution patterns due to renewables connected to transmission, distributed energy resources connected to the distribution system and the operation of electricity markets warrant that historical load and generation conditions be modeled in offline studies on a continuous basis instead of using the traditional peak load cases for Operations Planning studies...
The auxiliary line loss management system in Hebei grid is developed. The data of system are taken from EMS. After getting data from EMS, state estimation will be carried out periodically. The ground state of power flow is from the results of state estimation. The hardware configuration of system is introduced. A data receiving server is configured to receive model, graphic and data in auxiliary line...
On-line power system analysis enables to make power mode-related decision based on information available at real time. The quality of the studies and efficiency of power system operation are closely associated with the accuracy of the power system models. Accurate and quick decision based on analysis on real time data has been necessary for making operational plan under the deregulation of power system...
Powerlink Queensland is currently in the advanced stage of implementing a CIM-based enterprise-wide network asset model maintenance system. This model allows a single common repository for the planned and operational network model for use by planning, operations, EMS and protection. Planners are able to enter future projects with multiple possible scenarios with the capability to move the projects...
Rigorously speaking, power systems state estimation (SE) results aim at allowing the operator to take decision in order to assure network security. Therefore, in order to assure reliable information, SE results must be obtained through a very robust algorithm. In this work, the algorithm employed to solve the state estimation problem is based on the orthogonal iteratively re-weighted least-squares...
