The course is aimed at introducing some basic concepts on power system economics, including the reference market models and metrics along with some traditional and emerging methodologies in the simulation of electricity markets. The course discusses basic economic principles and their applications to electricity markets, considering the specificities of electricity as a commodity and the very peculiar impacts of the power network under which the market runs. Reference market arrangements and models will be introduced to describe conceptually electricity markets. Network impacts on the market performance, biding strategies as well as congestion management methods will be discussed. Approaches for electricity markets modelling and simulation, under network constraints, will be presented. For the pool electricity markets, they would be based on the concept of market equilibrium under the framework of game theory; while in the case of bilateral electricity markets we will consider evolutionary equilibrium under the framework of dynamic multi-agent systems. Applications and exercises related to simple cases will be proposed and discussed.
