Two smart frequency control schemes are presented in this paper. The first one is an adaptive under-frequency load shedding (UFLS) scheme, and the second one is system frequency control scheme based on energy storage and wind farm. The UFLS is developed based on a new and simplified methodology for an estimation of the magnitudes of disturbances (EMD). Using the estimation results, the UFLS can be...
The main goal of this paper is to present a new methodology for the estimation of magnitudes of disturbances (EMD). This methodology can be utilized in the adaptive Low Frequency Demand Control schemes in the next generation of distribution and transmission networks. In the focus of this paper will be distribution networks, consisting of conventional consumers and mixed renewable energy sources. The...
