Advanced perspectives and implementation of dynamic security assessment in the open market environment

The paper provides a detailed overview of an on-going industrial-research project supported by the EU and involving a large Consortium of Industries, Research Centers, Universities and System Operators. The preliminary phase for analyzing and defining the requirements of a DSA (Dynamic Security Assessment) tool to be included in the EMS (Energy Management System) environment is reported. The decision process to define the hardware and software architecture adopted for the implementation of a prototype is explained. The main features of an advanced DSA tool should allow assessing and improving the network dynamic security into a deregulated market environment. The project development is subdivided into three phases (project requirements and calibration, prototype system development, on-site experimentation) that are reported in the paper. The theoretical bases of the application functions included in the DSA (TSA – Transient Stability Assessment, VSA – Voltage Stability Assessment, TS – Training Simulator and MS – Market Simulator) are described into detail. The final product will be tested on the field at two experimental sites provided by two existing TSOs (Transmission System Operators). The paper also reports the set-up of suitable scenarios for the validation phase of the DSA tool
