This book was released on 2018-11-20 with total page 199 pages. Available in PDF, EPUB and Kindle. Book excerpt: This thesis is about the design and the implementation of a resilient grid operation for the distribution grid. This research question is induced by the advancing of three trends: Decarbonisation, decentralisation and digitalisation. These three trends transform the hitherto passive distribution grid into an active system that contains an active operation. The term “resilience” describes capabilities of the system to absorb, to adapt, and to recover from faults and disturbances. This concept is realised on the one hand with the choice of the operation architecture, on the other hand for the choice of possible methods and functions. This thesis develops a distributed-hierarchical operation architecture. For this architecture several methods have been developed that optimally benefit from the operation architecture and that allow the fully automated operation of the distribution grid. For that purpose a heuristic optimisation has been developed to solve problems like voltage profile violations and congestions. Another important method, especially with regard to resilience, is the self-healing capability to resupply clients after permanent faults.

Available in PDF, EPUB and Kindle. Book excerpt: RESILIENCY OF POWER DISTRIBUTION SYSTEMS A revolutionary book covering the relevant concepts for resiliency-focused advancements of the distribution power grid Most resiliency and security guidelines for the power industry are focused on power transmission systems. As renewable energy and energy storage increasingly replace fossil-fuel-based power generation over the coming years, geospatially neighboring distributed energy resources will supply a majority of consumers and provide clean power through long transmission lines. These electric power distribution systems—the final stage in the delivery of electric power—carry electricity from the transmission system to individual consumers. New distributed devices will be essential to the grid to manage this variable power generation and enhance reliability and resilience while keeping electricity affordable as the world seeks solutions to climate change and threats from extreme events. In Resiliency of Power Distribution Systems, readers are provided with the tools to understand and enhance resiliency of distribution systems—and thereby, the entire power grid. In a shift from the present design and operation of the power system, the book is focused on improving the grid’s ability to predict, adapt, and respond to all hazards and threats. This, then, acts as a guide to ensure that any incident can be mitigated and responded to promptly and adequately. It also highlights the most advanced and applicable methodologies and architecture frameworks that evaluate degradation, advance proactive action, and transform system behavior to maintain normal operation, under extreme operating conditions. Resiliency of Power Distribution Systems readers will also find: Chapter organization that facilitates quick review of distribution fundamental and easy-but-thorough understanding of the importance of resiliency Real-world case studies where resilient power systems could have prevented massive financial and energy losses Frameworks to help mitigate cyber-physical attacks, strategize response on multiple timescales, and optimize operational efficiencies and priorities for the power grid Resiliency of Power Distribution Systems is a valuable reference for power system professionals including electrical engineers, utility operators, distribution system planners and engineers, and manufacturers, as well as members of the research community, energy market experts and policy makers, and graduate students on electrical engineering courses.

Download or read book Quantifying the Resilience of Future Distributed Grids written by Lien Van Schepdael and published by . This book was released on 2016 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Smart distributed power systems are an important part of the energy shift that is currently taking place. Electricity generation, as well as power system control is moving from central operation towards local distribution grid operation, mainly due to the new possibilities that come along with distributed energy resources (DERs). These allow local consumers to generate their own electricity (prosumer), and offer support services to the grid, such as frequency control for example. Smart distributed grids can improve the local operation of DERs by coordinating demand and supply in real-time, and as such improve the power quality of the distribution grid, as well as improve the security of energy supply on local level. However, intelligent control systems, such as design of the H2020 project EMPOWER that will be used in this work, bring along complex new interconnections in the distribution grid, that may lead to increased risk of failure propagations in the distribution grid. As this, and several other challenges of the smart distributed grid could counteract the anticipated benefits, the need arises to evaluate how well an intelligent control system can cope with constantly evolving interconnections in the distribution grid, with the addition of new technologies, with the grid vulnerabilities regarding cyber security, etc. Evaluating how a system behaves when going through changing conditions, or when undergoing a disturbance, can be defined as resilience analysis, and this is what this thesis will be about. First, resilience will be defined in the context of smart distributed power systems through an extensive literature review, after which a resilience framework will be developed, based on the existing EMPOWER smart distribution grid. The technical characteristics, as well as the functionalities of the system will be defined and represented in an entity-relationship model. This model will serve as a basis to assess the level of dependencies that each main system functionality has in relation to three elements: the physical infrastructure of the system, its socio-economic environment, and the ICT network. Moreover, the attributes, or properties of the system components will be used to formulate resilience indicators against different types of disturbances of the smart distribution grid.

Download or read book Resilient Microgrids Through Software defined Networking written by Lingyu Ren and published by . This book was released on 2017 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Multiple major blackouts had occurred in the U.S. power distribution system highlighting the importance of enhancing electricity resiliency. Microgrid is the new paradigm incorporating high flexibility and reliability in power supply. It allows various distributed energy resources and loads to be integrated and coordinated as an intelligent entity through control and communication infrastructure. Microgrid control technologies have been continuously developed over 20 years. However, there is still a lack of communication architecture that is able to provide fast, reliable and elastic services for multi-level data transmission and adaptable network management. This dissertation solves this intractable problem by integrating programmable networks into microgrid to provide flexible and easy-to-manage communication solutions, thus enabling resilient microgrid operations in face of various cyber and physical disturbances. Both theoretical study and experimental tests have shown that the novel software-defined networking (SDN) based communication architecture can significantly improve the microgrid emergency control performance and expedite the development of microgrid applications. While providing resilience benefits to its local customers, a single microgrid can hardly contribute to the resiliency of the main distribution grid. Recent research shows interconnecting individual microgrids to form a networked microgrids community offers a new, more resilient solution for distribution grid. To support this innovation, this dissertation significantly extends the SDN-based communication architecture to achieve fast power support among microgrids, transforming isolated local microgrids into integrated networked microgrids capable of achieving the desired resiliency, elasticity and efficiency. Further, a novel event-triggered communication scheme is devised to enable distributed power sharing among microgrids in both the transient period and the steady state, a capability previously unattainable using existing technologies. This structure is validated through a cyber-physical Hardware-in-the-Loop (HIL) testbed designed in this dissertation for testing and prototyping networked microgrids technologies. One of the multifaceted benefits of the SDN-based architecture is that it provides a platform with open data access for the development of various advanced microgrid applications. As an instance, a generalized microgrid power flow (GMPF) algorithm is developed as an essential tool for control design and microgrid planning. Power flow analysis for islanded microgrid is a challenging problem due to the lack of means to incorporate the hierarchical control effect. This dissertation bridges the gap by introducing three novel GMPF techniques: 1) it introduces the generalized distributed generator (DG) bus and the adaptive swing bus to model the DGs’ behaviors; 2) the droop based power flow is used to initialize the secondary control adjustment; and 3) three types of secondary control modes are developed within a double loop framework. GMPF has proved to have excellent convergence performance and be able to provide information of power sharing and voltage regulation under different control modes, which makes it a powerful tool for microgrid planning, control design, and energy management, etc.
