Flexibility in Adaptation Planning: When, Where and How to Include Flexibility for Increasing Urban Flood Resilience (IHE Delft PhD Thesis Series)

by Mohanasundar Radhakrishnan

The magnitude and urgency of the need to adapt to climate change is such that addressing it has been taken up by the United Nations as one of the sustainable development goals - Goal 13 (SDG13) in 2015. SDG13 emphasises the need to strengthen resilience and adaptive capacity to climate related hazards and natural disasters. Coping with urban floods is one of the major needs of climate adaptation, where integration of climate change responses into flood risk management policies, strategies and planning at international, national, regional and local levels is now the norm. However, much of this integration lacks effectiveness or real commitment from stakeholders involved in adaptation planning and implementation. Hence this research has focused on integrating flexibility based adaptation responses into an urban flood risk management context. The research has synthesised flexible adaptation practices from several disciplines including information technology, automobile and aerospace manufacturing. The outcomes of the research are brought together in a framework for structuring local adaptation responses and an adaptation planning process based on flexibility concepts. The outcomes provide a way to assist with the identification of the appropriate nature and type of flexibility required; where flexibility can best be incorporated; and when is the most appropriate time to implement the flexible adaptation responses in the context of urban flooding.

Flexibility in Electric Power Distribution Networks

by Hassan Haes Alhelou Ehsan Heydarian-Forushani Pierluigi Siano

High penetration of renewable energy sources (RESs) imposes several techno-economic challenges to distribution system operators (DSOs) due to their variability in power generation and hence, increases the need for additional operational flexibility. Operational flexibility aims at securely covering the possible variations at least cost using emerging flexible alternatives or designing novel local market mechanisms to incentivize flexibility providers. In such a situation, the DSOs can use the potential of flexible options such as Energy Storages (ESs), Demand Response (DR), Plug-in Electric Vehicles (PEVs) or on-site fast run generators. However, each of the mentioned flexible resources has its own specific characteristics and requirements that should be taken into account and this raises the problem complexity. Optimal network reconfiguration schemes are also the other solution for increasing power system flexibility at distribution level. There is a great research gap related to renewable-based distribution network planning with flexibility point of view. Therefore, this book aims to discuss the additional flexibility needs introduced by RESs and describe general approaches to analyze the need for and provision of additional flexibility in future distribution networks at both planning and operational time frames. This book successfully suggests new solutions and techniques to increase the flexibility in distribution systems. This book also highlights the needs for moving towards smart distribution grids in order to enhance the flexibility in modern and future power systems.

Flexibility Measurement in Production Systems: Handling Uncertainties in Industrial Production

by Sven Rogalski

The requirements for production systems are constantly changing as a result of changing competitive conditions. This poses a challenge for manufacturers in the various branches of industry and creates an ever-increasing need for flexibility.With this as a background, this book explores the current developments and trends as well as their impact on today’s production systems. It also compares known strategies, concepts and methods used to achieve production flexibility. Similarly, the practical knowledge and current research will be drawn upon and subjected to a sound scientific analysis, through which the technical and organizational flexibility ranges can be measured in their application in a production system. The convenience and usefulness of this concept for manufacturers is substantiated by its implementation in a software tool called ecoFLEX and its practical application, based on extensive examples. This illustrates how flexibility flaws can be quickly identified, classified and properly disposed of using ecoFLEX. This tool helps to close the gap between ERP / PPS systems and digital factory planning tools.

Flexible and Generalized Uncertainty Optimization: Theory and Approaches (Studies in Computational Intelligence #696)

by Weldon A. Lodwick Luiz L. Salles-Neto

This book presents the theory and methods of flexible and generalized uncertainty optimization. Particularly, it describes the theory of generalized uncertainty in the context of optimization modeling. The book starts with an overview of flexible and generalized uncertainty optimization. It covers uncertainties that are both associated with lack of information and are more general than stochastic theory, where well-defined distributions are assumed. Starting from families of distributions that are enclosed by upper and lower functions, the book presents construction methods for obtaining flexible and generalized uncertainty input data that can be used in a flexible and generalized uncertainty optimization model. It then describes the development of the associated optimization model in detail. Written for graduate students and professionals in the broad field of optimization and operations research, this second edition has been revised and extended to include more worked examples and a section on interval multi-objective mini-max regret theory along with its solution method.
