2012-02 Optimisation and Simulation Methods for Large Power Systems
May 2-4, 2012

Objectives
The operational environment of modern power systems has shown an increasing degree of uncertainty due to many reasons such as intermittent renewable generation, load evolution and unforeseen topological changes in the internal/external system. In order to carry out off-line security and reliability assessment studies, it is necessary to construct realistic steady state operating points. The need for determining such steady state conditions is typically encountered when the Transmission System Operators try to identify potential problems ahead in time or root-causes of encountered problems after the facts. Because of the diversity of questions and viewpoints to be addressed, the tremendous complexity of electric power systems and the existence of a large number of nonlinear constraints, the construction of realistic steady state operating points for practical large power systems is intrinsically an extremely difficult task.
A classical Security Constrained Optimal Power Flow (SCOPF) tool can be generally used for conducting security assessment studies. This tool allows the finding of optimal settings, according to a given objective, of some control means (e.g. generators active/reactive power, transformer taps, reactive power of shunt compensation banks, start/shutdown of generators, etc.) that satisfy operational constraints (e.g. branch power flow, voltages, etc.) under pre-and post-contingency states. Besides, the SCOPF tool must model accurately special new devices like PST, HVDC and FACTS. Special emphasis is also put on the effective coordination between corrective actions and preventive actions.  Furthermore, a probabilistic constrained load flow method can be applied while additional power system studies can be conducted concerning the relations between voltage stability and maximum power transfer conditions.
Power system reliability assessment studies are usually conducted by using appropriate methods that realistically simulate the system operation by taking into account all relevant features and operational practices.
The Course has been designed to provide a solid understanding of the major issues concerning the planning and operation of modern electric power systems with a substantial penetration of distributed generation, especially, from renewable energy sources. More specifically, the following topics will be addressed:
•    Optimisation in decision making.
•    Challenges of current Security Constrained Optimal Power Flow computations.
•    Role of discrete variables in modelling aspects and their handling.
•    Steady state modelling of special devices (PST, HVDC, FACTS).
•    Dealing with uncertainty in day-ahead operational planning (the worst-case approach).
•    Handling of huge amount of post-contingencies constraints.
•    Performance issues on Pan-European network.
•    Probabilistic constrained load flow method.
•    Voltage stability and maximum power transfer conditions.
•    Reliability and operational performance of large power systems.

This Course is intended for all technical staff, engineers and managers from electric power utilities, independent generating companies (including renewable sources), electricity regulators, system operators, industrial customers, manufacturing and consulting companies as well as educational and research institutions who deal with the planning and operation issues of modern power systems. The number of participants is limited.
