The course presents methodological and technological aspects for the control and management of electrical systems for energy in the light of changes related to the electricity market and renewable energy resources. Dynamic models of production and transmission systems will be obtained and problems related to: economic definition of the operating point, continuity of service and control under normal conditions (frequency-power and voltage regulation), alert and emergency will be addressed.
The course aims to present the methodological and technological aspects for the control, management and protection of electrical energy systems. Starting from the conditions imposed by the free electricity market, problems related to the definition of the work point, continuity of operation (blackout prevention) and control aspects under normal, alert and emergency conditions are faced.
The course presents with a systemic and interdisciplinary approach the methodological and technological aspects for the control and management of electrical systems for energy in the light of the changes related to the electricity market and renewable energy resources.
At the end of the course the student will have acquired specific knowledge and sensitivity on the structure of a modern electrical system, on modeling issues of energy production and transmission systems, on the economic aspects for the management of the syesso system including market problems. electric.
The economic working point of an electricity system will be identified by means of economic dispatching techniques and this modality will be compared with the organization and management of the electricity market.
System modeling tools and the Basic Control Fundamentals course will be used to define dynamic models of electricity production and transmission systems for the participation of power plants in the supply of grid services to the electricity system in the frequency regulation modes. and active and voltage control powers.
Topics relating to continuity of service and control under normal conditions (frequency-power and voltage regulation), alert and emergency will also be presented from the results of European projects that involved the DITEN-IEES (Intelligent Electric Energy Systems) reference laboratory.
The course is based on theoretical lessons, seminars and exercises with the development of application examples. The lessons are complemented by application exercises and seminars on topical issues with the presentation of "test cases" (liberalized energy market, dynamic security assessment, emergency management). Technical visits are planned to Centers for the management and control of electrical networks and to companies that build control and protection systems such as ABB, TERNA, RSE, etc.
The topics covered are highly topical and offer significant perspectives for a master's degree thesis on research projects coordinated by the teacher and in collaboration with Italian and international companies in the electrical energy sector.
(1) Generalities on Electrical Systems for Energy: General considerations on process control. The electrical system as a" process "to be controlled. Choice of the operating point. (2) Power and frequency control: Dynamics and control of frequency and active power: primary regulation of an isolated group and network. (3) Modeling of groups for generation: hydroelectric, thermoelectric, turbogas plants. Primary regulators: construction diagrams and setting up of parameters. Plant regulation thermoelectric: turbine follows, boiler follows, coordinated regulation; (4) Distributed Generation: Models of the most common groups for generation with renewable and / or similar sources and their integration into the network; (5) Regulation and control of interconnected systems: secondary regulation : schemes: centralized regulation; schemes of the AGC - Automatic Generation Control type. (6) Primary voltage regulation for production groups: cont excitation roll of alternators, simple schemes for a "brushless" regulator; primary static regulators. (7) The EMS - “Energy Management Systems”. Typical functions of an EMS. The dispatching of active powers. (8) Preventive safety assessment. Direct methods for the evaluation of transient stability, energy functions and hybrid methods. Practical examples made at control centers. Operator training simulators. (9) Control in emergency conditions: The shedding of the load. Control of the load in relation to the market. (10) Economics of Electric Systems: the liberalization of the energy market and implications for the management of energy producers (primary service and auxiliary services). Methodologies and architectures for the electricity market: types of market; the markets for the Italian system (day-ahead market, adjustment markets, dispatching services).
