Subject fundamentals
The course is focused on the main technical-economic issues related to the power systems operation in the competitive electricity market context, with special reference to power plants and bulk transmission system.
Expected learning outcomes
The course will favor the learning of the basic knowledge needed in understanding the operation of power systems in the market framework. The knowledge can be articulated into two categories strictly interacting: technical and economic knowledge. The first are related to the steady-state and dynamic models for power system operation and control under normal conditions and emergency while the latter are focused on the economic efficiency of the electricity markets and on the analysis of market equilibria.
The aforementioned knowledge will be exploited by the students to perform technical-economic analysis of specific operative cases allowing for a development of individual skills in the assessment of alternative choices in the power systems operation.
Prerequisites / Assumed knowledge
Basic notions of mathematics and geometry, power systems analysis.
Contents
' The world Energy scenario; power systems and electricity market structure, trend in consumption, capacity, production costs for electricity, price fixing mechanism, structure for the tariffs; the Italian electricity market.
' Power plants and substations: structure and operation of power plants, electric wiring in substations; circuit breakers, choice of transformers, bay structure, aerial and cable lines, auxiliary services.
' Protection relaying: overcurrent protection and machinery faults, line and busbars protection, transformer and generator protection.
' Overvoltage and insulation: internal and lightning overvoltages, standardized waveforms, coordination of the insulation.
' Power systems vulnerability and security: classification of the operative states, contingency analysis, indices for security assessment, n-x security, vulnerability and risk in power systems.
' Power economics: prices, revenues and profits; supply and demand curves, profit and revenues maximization, demand elasticity, market equilibria and microeconomic metrics; market models and levels of competition.
' Optimization in power systems: optimal dispatch in thermal power plants, hydro-thermal optimal dispatch, optimal power flow and algorithms also with security constraints, optimization in the competitive markets, unit commitment.
' Electricity markets; origins of the electricity industry, structure, model and market players, demand and supply bids, price fixing mechanism, network constraints impacts, congestion management, zonal prices, transmission rights, market power analysis, ancillary services, reserve management , allocation of the losses, analysis of the Italian electricity market, green certificates market.
' Financial analysis of the investments: investments, capital and interest rate, financial mathematics, cash flow analysis, assessment of the investments, indices for financial analysis.
Delivery modes
Several classes in the computer lab will be devoted to make the students familiar with the analysis of power systems based on the SW tools that will be provided.
Texts, readings, handouts and other learning resources
The slides of all the lectures and the task assignments for each practical work in the computer lab will be assigned.
Assessment and grading criteria
The final examination will be an oral exam. The exam will focus on the topics of the lectures and practical work and will be structured into three questions with a maximum score of 10 point for each question.
