T2B: "Volt-VAR Control to Peak Load Relief and Energy Efficiency in Distribution Smart Grids"

The approach called Conservation Voltage Reduction (CVR) can be defined as being the practice of controlling the voltage levels on the network in order to promote a reduction in energy demand, considering that loads in the medium voltage (MV) networks are predominantly voltage dependent. It can be considered a form of demand management, especially in networks with a strong presence of residential and commercial customers.

In this tutorial, we will address concepts of CVR and IVCC settings and present load models in order to better represent the loads in MV networks. Then will be presented and discussed several cases of CVR application performed by different distribution companies in the world. Concluding, case studies will be shown with the presence of OLTC, AVRs, capacitors and distributed generators. Special highlights will be emphasized for models and forms of voltage control in distributed generators. The CVR applications will allow us to describe the positive economic and technical benefits showing significant values of energy savings for a typical day of operation, and peak load relief important in both distribution and the transmission system. Additionally, these advantages are obtained while maintaining the supply voltage quality for all consumers. Other important gains can be noted in reduction of power losses and the maintenance of the power factor within the specified range.

T1D-T2D: "Techno-economic optimisation and flexible planning under uncertainty of smart distribution networks, Microgrids and district energy systems"

Dr. Eduardo Alejandro Martínez Ceseña, The University of Manchester, UK, E-mail: eduardo.martinezcesena[Q]manchester.ac.uk

Emerging environmental concerns and technological developments are leading to an increased penetration of distributed energy resources (DER) in distribution networks. The efficient accommodation of these resources is a grand challenge. However, owing to the rise of Information and Communications Technologies (ICT) and Demand Side Response (DSR) in a Smart grid context, distributed energy technologies can be more and more readily dispatched and coordinated to meet different needs. This offers unprecedented opportunities to enhance the operation, design and business cases of innovative technologies in smart distribution networks. However, powerful mathematical techniques are needed to deal with different types and levels of uncertainty that characterize future energy systems, from both the operational and planning perspectives.

This tutorial overviews different theoretical frameworks that have been recently developed in various projects at the University of Manchester in the area of techno-economic optimisation and flexible planning of innovative distributed energy systems with large scale penetration of DER in the presence of small scale (short term) and large scale (long term) uncertainties.

Dr. Mancarella received the Ph.D. degree in Electrical Engineering (Power Systems) from the Politecnico di Torino, in Italy in 2006. He is currently a Reader in Future Energy Networks and part of the Electrical Energy and Power Systems at the University of Manchester. He has co-authored roughly 100 research papers and is currently involved in about 15 research projects sponsored by the EPSRC, the European Commission, and various industrial companies, in the area of techno-economics of multi-energy systems, investment under uncertainty for integrated energy infrastructure, business cases for smart grid technologies, and risk and resilience analysis of future networks.

Dr. Martínez Ceseña received the Ph.D. degree in Power Systems from the University of Manchester, UK, in 2012. Since obtaining the degree, he has worked as a Research Associate in the School of Electrical and Electronic Engineering in the same institution. Dr. Martínez Ceseña has co-authored about 20 research papers and has participated in several European and UK research projects including ADDRESS, APS, Capacity to Customers and COOPERaTE; specifically, in work streams related to the integration of new smart network solutions, economic and financial assessment under significant sources of uncertainty, real options theory and business models.
