This paper describes one approach to find two optimum energy storages (ESs) to build a hybrid system which is part of a virtual power plant. In this paper it means the combination of the hybrid energy storage system and wind power plant (WPP). The discussed approach is applied in a case study on the power market in western Denmark. The optimum ESs are selected based on the highest net present v...

in the last years of the twentieth century and the early years of the twenty first century, globalization with all its aspects and effects, has laid a ground which has originated and/or deepened structural weaknesses of states, their inability to answer the citizens’ demands and functional crisis of states. formation of international institutions, international non-governmental organizations (n...

-  Power system state estimation is a central component in energy management systems of power system. The goal of state estimation is to determine the system status and power flow of transmission lines. This paper presents an advanced state estimation algorithm based on weighted least square (WLS) criteria by introducing virtual meters. For each bus of network, except slack bus, a virtual meter...

The virtual power plant (VPP) can aggregate small-scale distributed resources to provide flexibility for the transmission system. provision capability of VPP is restricted by technical operating limits distribution system which are connected. To facilitate while securing operation local system, this paper leverages dynamic line rating (DLR) enlarge region. region defined as allowable range acti...

Virtual power plant (VPP) provides a flexible solution to distributed energy resources integration by aggregating renewable generation units, conventional plants, storages, and demands. This paper proposes novel stochastic adaptive robust optimization (SARO) model for determining the optimal self-scheduling plan VPP’s participation in day-ahead energy-reserve market. We consider exogenou...
