Dispatch-aware Optimal Planning of Active Distribution Networks including Energy Storage Systems

Ji Hyun Yi

The thesis develops a planning framework for ADNs to achieve their dispatchability by means of ESS allocation while ensuring a reliable and secure operation of ADNs. Second, the framework is extended to include grid reinforcements and ESSs planning. Finall ...

Leveraging industrial biorefineries for the energy transition

François Maréchal, Julia Granacher

Biorefineries hold the potential to provide products and energy carriers at reduced environmental impact compared to their fossil-based counterparts. Thus, they can contribute to the decarbonization of sectors in which electrification of demands is challen ...

Reliable Dispatch of Active Distribution Networks via a Two-layer Grid-Aware Model Predictive Control: Theory and Experimental Validation

Mario Paolone, Rahul Kumar Gupta, Antonio Zecchino, Ji Hyun Yi

Dispatching active distribution networks (ADNs) is an energy-intensive application that, if implemented via battery-energy storage systems (BESSs), can require a large capacity of these assets in order to fully balance the uncertainties caused by the stoch ...

Online Battery Storage Management via Lyapunov Optimization in Active Distribution Grids

Jean-Yves Le Boudec, Cong Wang, Eleni Stai

We consider low run-time complexity power management in distribution grids with renewable energy sources (RESs) and batteries, where forecasts are unavailable. We propose iterative Lyapunov Real-time Control (iLypRC), a fast online algorithm, which does no ...

Reversible solid-oxide cell stack based power-to-x-to-power systems: Comparison of thermodynamic performance

François Maréchal, Jan Van Herle, Ligang Wang, Tzu-En Lin, Philippe Aubin, Maria del Mar Perez Fortes, Yumeng Zhang

The increasing penetration of variable renewable energies poses new challenges for grid management. The economic feasibility of grid-balancing plants may be limited by low annual operating hours if they work either only for power generation or only for pow ...

Cooperative energy management of a community of smart-buildings: A Blockchain approach

Maher Kayal, Olivier Valentin Henri Van Cutsem

Demand Response (DR) is progressively moving from a centralized, unidirectional structure to a set of advanced decentralized mechanisms that better balance distributed supply and demand. This paper presents a decentralized cooperative DR framework to manag ...

Siting and Sizing of Energy Storage Systems: Towards a Unified Approach for Transmission and Distribution System Operators for Reserve Provision and Grid Support

Mario Paolone, Fabrizio Sossan

This paper presents a method to determine the optimal location, energy capacity, and power rating of distributed battery energy storage systems at multiple voltage levels to accomplish grid control and reserve provision. We model operational scenarios at a ...

Optimal path to a high share of distributed PV in low-voltage distribution grids

Lionel Benjamin Bloch

To limit global warming, the energy transition from fossil fuels to renewables is one of the main challenges of this century. This transition will help decrease our CO2 emissions, create jobs, contribute to a broader revenues distribution, improve energy s ...

Constrained hierarchical networked optimization for energy markets

Lorenzo Nespoli

In this paper, we propose a distributed control strategy for the design of an energy market. The method relies on a hierarchical structure of aggregators for the coordination of prosumers (agents which can produce and consume energy). The hierarchy reflect ...

Methods and Performance Assessment of PMU-based Real-Time State Estimation of Active Distribution Networks

Styliani Sarri

The evolution from passive to Active Distribution Networks (ADNs) is producing large changes in the operation of these electrical systems. In particular, violations of grid operational constraints, higher dynamics and limited amount of controllable resourc ...

Valuing quantity flexibility under supply chain disintermediation risk

Isik Bicer

We consider a supply chain with one supplier and one retailer in which the parties develop a quantity flexibility contract to specify the conditions of procurement activities. The contract allows the retailer to adjust the initial order quantity after the ...

The Facilitation of Mini and Small Hydropower in Switzerland : Shaping the Institutional Framework (with a Particular Focus on Storage and Pumped-Storage Schemes)

Nicolas Crettenand

The electricity sector in Switzerland is undergoing important changes following the liberalisation process and the facilitation of renewable energy technologies. Furthermore, the phasing out of nuclear power will increase the demand for new domestic electr ...

Pump-storage small hydropower as an example of co-evolution between institutions and technologies

Nicolas Crettenand

The aim of this paper is to explore the storage and pump-storage application of small hydropower as an example of co-evolution between institutions and technologies. The context of the research is given by the liberalisation of the electricity sector and t ...

Generation Capacity Investments in Competitive Electricity Markets: A Preliminary Assessment after 10 years of Liberalization in Europe

Matthias Finger, Bastian Wolfgang Schwark

Balancing supply and demand in energy markets is not an easy task. Competitive markets oblige private actors to justify their investments towards their shareholders by appropriate rates of return. Consequently, electricity markets may lead to under-investm ...
