Determination of Remedial Actions Taking into Account Various Operational Rules

In most countries, power system operators are legally obliged to guarantee system security. If system security is endangered, the use of remedial actions is required. Thereby the operation points of grid equipment and grid users have to be adopted with regards to N-1-criterion. The determination of the remedial actions is performed as a result of OPF and SCOPF algorithms. In deregulated power system the formulation of the necessary objective function is hard to define. This paper presents a method to determine remedial actions with various operational rules. Rather the solution indicates the existence of solutions fulfilling the most important N-1-criterion. The proposed method is validated by a numerical case study with a standard reference grid.
