Obiettivi dell'insegnamento

The course focuses on the study of the evolution of electricity systems needed to enable a significant supply from renewable energy sources (RESs). In this perspective, we focus on the impact of RESs on the electricity system (market and networks). Market rules should ensure that conventional power stations are suitably operated even in the presence of large contributions from renewable generation; the different role that will be covered from RES generators that have some degree of programmability, as mini-hydro, biomasses and biogas, will also be highlighted. The impact on networks will be covered: transmission system will be mainly impacted by the massive contribution of wind energy; as for distribution networks (DNs), both MV and LV, it will be highlighted as the current structure does not allow the full integration of RESs generation into the system. The evolution of DNs will be addressed in the context of smart grid perspective to which distribution systems are gradually moving. For this topic, some details about technical solutions, about the use of ICT as enabling key will be given. Finally, some case studies and real life implementations will be described, with the relevant costs and benefits.


Risultati di apprendimento attesi

Lectures and exercise sessions will allow students to:

  • Analyze and understand the problems deriving from the evolution of distribution grids towards a smart grid paradigm
  • Identify and define the constraints, the interactions, and the different control techniques related to the introduction of distributed generation into an LV distribution network
  • Identify and define the problems and the possible solutions related to the installation and usage of energy storage systems 

By successfully passing the final test the student is able to:

  • Apply the acquired knowledge to real-life cases (possibly different from those analyzed during the lectures)
  • Select and size an energy storage system according to the specific functions requested by DSO or end-user
  • Define and write the specifications for the connection of renewable energy production plants with or without energy storage systems to LV and MV networks
  • Autonomously judge and make decisions
  • Communicate and explain in a clear way the selected solutions.

 


Argomenti trattati
  • The national regulatory framework. Italian National Renewable Energy Action Plan. Statistical data on RESs in Italy. RESs generation in Italy: the Green Certificates. Photovoltaic solar generation in Italy: the feed-in premium scheme. Criteria and procedures for granting the support. Legislative/regulatory framework.

  • Impact of RESs on electricity markets. Impact of RESs on electricity markets. Impacts on Italian Power Exchange (IPEX) (low market liquidity, high price volatility, etc.). Impacts on Italian dispatching services market (MSD) (more adequacy and security problems). Regulatory resolutions and perspective.

  • Impact of RESs on transmission and distribution network planning and operation. Integration of RES (transmission networks); distributed generation (DG) in the power system (distribution networks): a hosting capacity approach. Limits to DG on Italian MV networks.

  • Network open access. Technical rules for connection for MV and LV networks (photovoltaic; small CHP); closed distribution systems.

  • Evolving networks toward smart grids. Active distribution networks: drivers of evolution and main purposes. New operation criteria for distribution networks: DG providing ancillary services; energy storage systems connected to transmission/distribution grids. Networks optimization with advanced metering infrastructure and smart meters. Electric vehicles and recharging infrastructure: characteristics, development, and impact on the network. ICT: shared vs dedicated communication infrastructures, performance requirements. The innovative functions of smart grids: automatic selection of faulty branches, microgrid and islanding operation (innovative Interface Protection with transfer trip, distribution network observability and central plant controller), advanced distribution management systems (DMSs), voltage control (and the contribution of DG to voltage control and network stability), emergency limitation/regulation of active power, monitoring of DG injections, enabling demand-response strategies (second generation smart meter and CHAIN 2 protocol). The new model of distribution network: overall system architecture.

  • Load forecasting techniques. Definition of the main problems related to load forecasting. Definition of ARIMA-based methodologies.


Prerequisiti

Students are required to know the principles of power systems analysis and control.


Modalità di valutazione

The course includes both theoretical and exercise lectures. All the topics taught during these teaching activities are subject to the assessment, which is composed of a written and an oral test.
The written test is made up of 18 multiple-choice (true/false) questions and two open-ended questions.
The oral test, besides verifying and confirming the aforementioned abilities, is aimed also to verify the ability of the students in making judgments.

Grading will be on the following basis:

Type of assessment

Description

Dublin descriptor

Written test

  • Questions on the course topics that require to have read and carefully studied the slides and the suggested bibliography.

1, 2

Oral test

  • Questions on the course topics, requiring a personal elaboration of the subjects, and the formulation of critical judgments.

1, 2, 3, 5

The oral test is optional. The maximum grade that can be attained with the written test is 27.
