Electric Power Market

Course Description

Power sector restructuring (organizational structures before and after restructuring). Implementation of classical economic theory on electric power system (liberalization, deregulation, reregulation, privatization). Market different design and organization (wholesale, spot, futures, forward, balancing, bilateral). Electric power market and ancillary systems market. Power Exchange (PX). Auction Types. System operators (minimal and maximal concepts). Costs (marginal, opportunity, stranded, variable, total?). Influence of ancillary services on market i.e. price of electricity. Systems for measurement and accountings in new environment. Mandatory and commercial services. Market power. Transmission congestion as results of market transactions.

General Competencies

Understanding new electric power companies’ structures. Knowledge about System operator role and importance in open market environment. Understanding connection between ancillary services market design and insurance of stabile and secure power system operation.
