Power System Operation in Market Environment

Subject description

Impact of electricity market on power system operation: the role of producers, consumers, transmission and distribution networks and their technical constraints, methods for static analyses, sensitivity analyses, optimal power flow calculation.

Ancillary services: load forecasting, reserves, active power and frequency control, reactive power and voltage control, methods for voltage collapse proximity assessment, ancillary service procurement. Power system reliability, security of supply, reliability indices, network adequacy. Deterministic and stochastic concepts in power system operation and energy markets.

The subject is taught in programs

Objectives and competences

Students will obtain an overview of power system operation in market environment. This course presents models of energy markets: physical market, financial markets, bilateral trading, organized markets: auction, intra-day market, continuous market, balancing market, cross-border trading, ancillary service procurement etc. Focus of this course is the impact of energy market on power system operation.

Teaching and learning methods

Lectures or seminars.

Expected study results

After successful completion of the course, students should be able to:

– develop mathematical models of basic elements of electric power system (generator, load, line, transformer),

– perform static analyses of power system operation in market environment (power flow calculation, contingency analyses, economic dispatch, unit commitment etc.),

– solve basic problems in the field of power system operation,

– develop optimization models and selection of appropriate optimization method for mathematical problems in the field of power system operation in market environment,

– assess electric power system reliability and economic feasibility of power system operation,

– interpret basic principles of electric energy and ancillary service markets.
