An evaluation of flexibility in the EU-project CoordiNet : Could flexibility markets be a solution to capacity shortage?

Abstract: This bachelor thesis examines the part of the EU-project CoordiNet based on Vattenfall Distribution AB and their commitment in the project. The aim and purpose of CoordiNet are to find possible solutions on capacity shortage through coordination between customer -DSO -TSO achieving a more efficient usage of the electrical grid.  The report evaluates the outcomes of the implementation of the CoordiNet project, focusing on the demonstration in Uppsala. An investigation of the flexibility market used in CoordiNet is made with the aim to examine the impact on capacity shortage. Additionally the report looks into the profits of making flexibility calls and how accurate the load forecasting for the project has been and its impact on the result. All the calculations and evaluations are based on analyses from the available data sets. Statistical methods are used together with diagrams to make the evaluation possible.  The conclusion is that CoordiNet and its flexibility market in Uppsala has led to reduced subscription overruns, which in turn has an positive impact on both the capacity in the electrical grid and also costs regarding excess charges. The load forecasting model used in the project proved to be better and more stable than the previous model and it is neither markedly affected by temperature or energy prices. This CoordiNet demonstration is the first one in Uppsala and to a large extent it has been a test period. There will be further demonstrations in the future and this first demonstration is a great learning experience for upcoming projects.
