Thesis
The use of batteries as backup in case of power outages is common in telecommunications networks, since they provide critical services and need to keep their services always online. These batteries are used in conjunction with antennas and other equipment, and strict safety usage rules must be considered in order to guarantee that they are always available in case of a power outage. Besides, the telecommunications operator could use these batteries in order to participate in the electricity market provided that the grid is reliable enough, as long as the safety usage rules are respected. Indeed, since the energy price varies over time, batteries can be used to avoid buying energy when this price is high, and recharged when the energy price is low, a behavior that will be denoted as a peak-shaving strategy. A second profitable way for a company to use its batteries is by performing load curtailments. Indeed, when the power demand of a country is greater than the production, the Transmission System Operator must take steps in order to stabilize the grid such as ask power plants to produce more energy. Another way is to ask energy-intensive consumers to reduce their consumption during a given time period (in which case they are said to perform a load curtailment), by offering them a reward in exchange. In this thesis, we consider the problem of optimizing the total energy costs using batteries installed for backup in order to participate in the energy market by performing peak-shaving and load curtailments, with the help of a proper batteries management. Our goal is to reduce the total energy operational expenses for the company, and maximize the rewards received by performing load curtailments. A study of the electricity market architecture in France is conducted to understand the demand, flexibility mechanisms and how the operational constraints in the use of batteries of a telecommunications operator interact with the energy market. We identified different challenges that were investigated individually to better understand the characteristics of the underlying optimization problem and thus to develop more efficient solving methods. For each one, mixed-integer linear programs and heuristics are then proposed to solve the related problem. Once we investigated and understood the individual challenges, we proposed mixed-integer linear programs and heuristics for the main problem of this thesis, which we prove to be NP-Hard, incorporating market energy prices and the availability of batteries. Finally, simulations based on realistic data from the French telecommunications operator Orange show the relevance of the models and heuristic proposed: these prove to be computationally efficient in solving large scale instances, resulting in significant savings and revenue through the optimized multi-battery energy storage management policies.

Energy crisis and carbon emission have become two seriously concerned issues universally. As a feasible solution, Energy Internet (EI) has aroused global concern once proposed. EI is a new power generation developing a vision of evolution of smart grids into the Internet. The communication infrastructure is an essential component to the implementation of EI. A scalable and permanent communication infrastructure is crucial in both construction and operation of EI. In this paper, we present an introduction and the motivation to the evolution from smart grid to EI. We also introduce a representative EI architecture, i.e., the future renewable electric energy delivery and management system. Four critical EI features are emphasized. Then, we summarize the essential requirements that EI systems have to meet. With several key supporting technologies, EI shall realize the optimal utilization of highly scalable and distributed green energy resources, so that the situation of severe energy source crisis and carbon emission can be efficiently relieved. Since an EI system might have extensively distributed consumers and devices, the guarantee of its reliability and security is extremely significant. The further specific exploration for challenges, including reliability and security, will be stated in this paper.

The growing challenges of Smart Micro-Grid can only be met if secure and fast information and communication technology (ICT) solutions are developed. In this paper, some of the ICT techniques are reviewed for smart micro-grid automation. Firstly, an overview of the role of ICT in grid distribution is explained with respect to electricity value chain in power distribution. Further, each domain in the value chain is analyzed with respect to ICT applications in power generation, transmission, distribution and consumption. ICT stands as a prominent driving force to enhance trustworthiness, security, and productivity of the power distribution through information exchange, regulated generation, demand management, and the active involvement of the end consumer. It helps evade peak hours and switch between renewable and other energy sources. When many consumers are subscribed to smart micro-grid system, the demand of its reliability and security can only be guaranteed through robust ICT applications. ICTs in smart micro-grid helps to advance power reliability and quality avoiding electricity blackouts. When automation, remote monitoring, supervision and controlling entities are integrated in substantial scale, security of the micro-grid system is challenged due to more flexibility accessibility and information openness. ICT challenges and issues in the smart micro-grid are discussed and next generation innovative micro-grid control center is explained to recognize the potential of ICTs in the smart micro-grid automation.

Currently, Advanced Metering Infrastructure (AMI) systems have equipped the low voltage section with a communication system that is being used mainly for metering purposes, but it can be further employed for additional applications related to the Smart Grid (SG) concept. This paper explores the potential applications beyond metering of the available channel in a Power Line Communication-based AMI system. To that end, IP has been implemented over Narrow Band-Power Line Communication (NB-PLC) in a real microgrid, which includes an AMI system. A thorough review of potential applications for the SG that might be implemented for this representative case is included in order to provide a realistic analysis of the potentiality of NB-PLC beyond smart metering. The results demonstrate that existing AMI systems based on NB-PLC have the capacity to implement additional applications such as remote commands or status signals, which entails an added value for deployed AMI systems.

Conference Paper
Micro grids are localized groups of electricity generators, energy storage systems, and loads with the possibility of operating both connected and disconnected from the distribution grid. This paper is focused on the automation of micro grids using heterogeneous communication networks; the new approach takes into account the need of reusing existing wired and wireless technologies and assets when planning and deploying new renewable power sources or energy storage systems into traditional (old) grids. The proposed system uses the IEC 61850 in order to guarantee the interoperability with the distribution grid. In addition, the possible synergies with industrial and building automation have been investigated using well-known automation protocols (such as PROFINET and Modbus TCP). The proposed system has been installed and tested in a real micro grid inside the campus of the University of Brescia. Design description, deployment report and result analysis are given, showing that the performance of the real system (i.e. reaction time less than 30 ms at grid level network over heterogeneous links) is in line with the application requirements.

Utilities, faced with increasingly limited resources, strive to maintain high levels of reliability in energy delivery by adopting improved methodologies in planning, operation, construction and maintenance. On the other hand, driven by steady research and development and increase in sales volume, the cost of deploying PV systems has been in constant decline since their first introduction to the market. The increased level of penetration of distributed energy resources in power distribution infrastructure presents various benefits such as loss reduction, resilience against cascading failures and access to more diversified resources. However, serious challenges and risks must be addressed to ensure continuity and reliability of service. By integrating necessary communication and control infrastructure into the distribution system, to develop a practically coordinated system of distributed resources, controllable load/generation centers will be developed which provide substantial flexibility for the operation of the distribution system. On the other hand, such a complex distributed system is prone to instability and black outs due to lack of a major ``infinite" supply and other unpredicted variations in load and generation, which must be addressed. To devise a comprehensive method for coordination between Distributed Energy Resources in order to achieve a collective goal, is the key point to provide a fully functional and reliable power distribution system incorporating distributed energy resources. A road map to develop such comprehensive coordination system is explained and supporting scenarios and their associated simulation results are then elaborated. The proposed road map describes necessary steps to build a comprehensive solution for coordination between multiple agents in a microgrid or distribution feeder. %In the first chapter, an introduction to the ever increasing idea of utilizing distributed energy resources ss presented. %Over the course of the recent years, it has become more clear that a nontrivial but viable solution to the problems of the aging electrical infrastructure, inefficiencies in transmission and distribution of electricity, crucial effects of blackouts and brownouts on economy and people's lives could be a smart grid which utilizes and coordinates all available resources toward a collective target which is beneficial to both customers and grid operators. Some of the related researches and reports was then reviewed and studied to understand where other researchers stand and which areas are overlooked.

A communication infrastructure is an essential part to the success of the emerging smart grid. A scalable and pervasive communication infrastructure is crucial in both construction and operation of a smart grid. In this paper, we present the background and motivation of communication infrastructures in smart grid systems. We also summarize major requirements that smart grid communications must meet. From the experience of several industrial trials on smart grid with communication infrastructures, we expect that the traditional carbon fuel based power plants can cooperate with emerging distributed renewable energy such as wind, solar, etc, to reduce the carbon fuel consumption and consequent green house gas such as carbon dioxide emission. The consumers can minimize their expense on energy by adjusting their intelligent home appliance operations to avoid the peak hours and utilize the renewable energy instead. We further explore the challenges for a communication infrastructure as the part of a complex smart grid system. Since a smart grid system might have over millions of consumers and devices, the demand of its reliability and security is extremely critical. Through a communication infrastructure, a smart grid can improve power reliability and quality to eliminate electricity blackout. Security is a challenging issue since the on-going smart grid systems facing increasing vulnerabilities as more and more automation, remote monitoring/controlling and supervision entities are interconnected.
