Chance-constrained optimization approach to transmission system security

FNR DFG INTER project ECHO

The intermediate workshop of the FNR INTER project ECHO (Chance-constrained optimization approach to transmission system security), a collaboration between LIST and Technical University of Ilmenau, has two goals:

• learning and obtaining feedback from internationally leading researchers and practitioners in these topics and
• disseminating our first research results.

The project ECHO project focuses on the security-constrained (or contingency-constrained) optimal power flow (SCOPF), and aims improving the decision-making for day-ahead planning of power system operation, i.e. to ensure a cost effective and reliable power system scheduling for every hour of the next day.

Power systems are facing increasingly uncertain operation conditions, due to growing amounts of fluctuating renewable generation. The deterministic version of SCOPF, which fits only the most likely forecasted scenario, is not anymore suitable since it may lead to either poorly sub-optimal or unreliable/risky operating conditions. To overcome this limitation, the ECHO project will develop a new SCOPF approach which manages the uncertainty via chance constrained optimization that enforces the set of constraints to satisfy a user-defined probability level. To this end, we resort to the inner-outer approximation method, which is a new theoretical advancement in the area of chance constrained optimization.
