Social impact based contingency screening and ranking
نویسندگان
چکیده
This paper develops a new index to rank the contingencies in different partitioned areas of networks. The new index considers the social and economic impacts of the contingencies and ranks them by using an overall index that combines these effects with technical factors. This overall index is implemented in the Western Systems Coordinating Council (WSCC) system. Load flow is run in different scenarios; and real power losses, Available Transmission Capability (ATC), and Expected Socially Unserved Energy (ESUE) are compared.

Cascade fuzzy neural network based voltage contingency screening and ranking
A method based on cascade fuzzy neural network (CFNN) comprising of a filter module and ranking module is proposed for online voltage contingency screening and ranking under known but uncertain loads. A new fuzzy performance index, which combines voltage violations and voltage stability margin following a contingency, is proposed for effective voltage security ranking. All the selected continge...
متن کاملSensitivity Based Network Contingency Ranking Using Newton Raphson Power Flow Method
In the area of power system planning and operation, contingency analysis plays an important role. In the present days, on-line security assessment is done by contingency ranking, with the help of various computer software, incorporating iterative method like Newton Raphson power flow for obtaining the magnitudes of different parameters. The motive of contingency ranking is to create a short lis...
متن کاملFast Voltage and Power Flow Contingency Ranking Using Enhanced Radial Basis Function Neural Network
Deregulation of power system in recent years has changed static security assessment to the major concerns for which fast and accurate evaluation methodology is needed. Contingencies related to voltage violations and power line overloading have been responsible for power system collapse. This paper presents an enhanced radial basis function neural network (RBFNN) approach for on-line ranking of ...
متن کاملContingency Ranking in Modern Power System by Exact and Precise Method
One of the important aspects of modern power system security assessment is the consideration of any contingencies arises due to unplanned or planned line outages leading to system overloads or abnormal system voltages. Several methods have been developed in the past few years to address this problem but computation time has been identified as the constraint making the process inefficient. Utili...
