Scalable Optimal Design of Incremental Volt/VAR Control using Deep Neural Networks
Sarthak Gupta, Ali Mehrizi-Sani, Spyros Chatzivasileiadis +1
Volt/VAR control rules facilitate the autonomous operation of distributed energy resources (DER) to regulate voltage in power distribution grids. According to non-incremental contr…
Optimal Design of Volt/VAR Control Rules of Inverters using Deep Learning
Sarthak Gupta, Vassilis Kekatos, Spyros Chatzivasileiadis
Distribution grids are challenged by rapid voltage fluctuations induced by variable power injections from distributed energy resources (DERs). To regulate voltage, the IEEE Standar…
Network-Aware Flexibility Requests for Distribution-Level Flexibility Markets
Eléa Prat, Irena Dukovska, Lars Herre +3
This paper proposes a method to design network-aware flexibility requests for local flexibility markets. These markets are becoming increasingly important for distribution system o…
Design of a Continuous Local Flexibility Market with Network Constraints
Eléa Prat, Lars Herre, Jalal Kazempour +1
To the best of our knowledge, this paper proposes for the first time a design of a continuous local flexibility market that explicitly considers network constraints. Continuous mar…
Learning Active Constraints to Efficiently Solve Linear Bilevel Problems: Application to the Generator Strategic Bidding Problem
Eléa Prat, Spyros Chatzivasileiadis
Bilevel programming can be used to formulate many problems in the field of power systems, such as strategic bidding. However, common reformulations of bilevel problems to mixed-int…
Market Integration of HVDC Lines: Cost Savings from Loss Allocation and Redispatching
Andrea Tosatto, Matas Dijokas, Danilo Obradovic +7
In the Nordic region, many interconnectors are formed by HVDC links, as Scandinavia, Continental Europe and the Baltic region are non-synchronous AC systems. This paper presents tw…
Second-Order Cone Relaxations of the Optimal Power Flow for Active Distribution Grids
Lucien Bobo, Andreas Venzke, Spyros Chatzivasileiadis
Convex relaxations of the AC Optimal Power Flow (OPF) problem are essential not only for identifying the globally optimal solution but also for enabling the use of OPF formulations…
HVDC Loss Factors in the Nordic Power Market
Andrea Tosatto, Spyros Chatzivasileiadis
In the Nordic countries (Sweden, Norway, Finland and Denmark), many interconnectors are formed by long High-Voltage Direct-Current (HVDC) lines. Every year, the operation of such i…
A modified version of the IEEE 3-area RTS '96 Test Case for time series analysis
Andrea Tosatto, Tilman Weckesser, Spyros Chatzivasileiadis
This report describes a modified version of the IEEE 3-area RTS '96 Test Case for time series analysis. This test case was originally developed to investigate the impact of the int…
Inexact Convex Relaxations for AC Optimal Power Flow: Towards AC Feasibility
Andreas Venzke, Spyros Chatzivasileiadis, Daniel K. Molzahn
Convex relaxations of AC optimal power flow (AC-OPF) problems have attracted significant interest as in several instances they provably yield the global optimum to the original non…
Market Integration of HVDC Lines: Internalizing HVDC Losses in Market Clearing
Andrea Tosatto, Tilman Weckesser, Spyros Chatzivasileiadis
Moving towards regional Supergrids, an increasing number of interconnections are formed by High Voltage Direct Current (HVDC) lines. Currently, in most regions, HVDC losses are not…
