In emerging electric power systems, increased transactions often lead to the situations where the system no longer remains in secure operating region. The flexible Ac transmission system (FACTS) controllers can play an important role in the power system security enhancement. However, due to high capital investment, it is necessary to locate these controllers optimally in the power system. FACTS...

Introduction of new technologies such as energy storage systems, electric vehicles, and distributed generation improved the characteristics of networks. On other hand, using these components in distribution systems improves system performances such as power losses. One of effective methods for improving system characteristics is distribution network reconfiguration. In this study, in addition t...

This paper presents a study to estimate the composition of an electric load, i.e. to determine the amount of each load class by the direct measurements of the total electric current waveform from instrument reading. Kalman filter algorithm is applied to estimate the electric load composition on a consumer side of a distributed power system. The electric load supplied from the different voltage ...

Electric distribution companies regulation has important effect on power system. Distribution services costing are done by two method, price base and performance base. Distribution company cost include operational and investment. Services quality, productivity improvement and etc are applied by benchmarking. With regard to different condition of companies, it is important that regulator benchma...

Electric power is the mainstay of a nation’s economy and the lifeline of industrial production and social life. All parameters of an electric grid, especially harmonic parameters, are related to the quality of electricity generated, which guarantees safe operation of electric equipment. Therefore, this design combines a web-based electric grid parameter measurement system with a video-monitorin...
