The Virtual Power Plants (VPPs) concept is increasingly spreading among the networks and among electrical utilities. This deliverable starts from the basic definition related to VPPs to pave a basic and shared knowledge of the topics discussed in edgeFLEX. Afterwards, the voltage control scenario, which applies on VPPs, is presented and detailed. This description offers a solid and clear environment in which the voltage control service can be tested and assessed.
The Deliverable describes the voltage control algorithm that has been delivered to WP4 as docker container for integration into the edgeFLEX architecture.

In this deliverable, we first focus on the definition of the 5G context of the edgeFLEX services and enablers. We describe our definitions of the 5G ICT requirements of edgeFLEX services and enablers and of 5G-powered ICT solutions to optimally support them, as well as timescales for the commercial deployment of these solutions.
Then, in the context of edgeFLEX 5G-powered solutions, we describe the novel Ericsson prototype 5G Device Management Application Programming Interface (API) and how our demonstration of it shows the increased ease of use and increased security and flexibility which this API offers to VPP and power system operators. We developed a graphical user interface (GUI) for the 5G Device Management API to visualise the features of the API being used to support edgeFLEX services.
In this study, we explore the optimization of virtual power plants (VPP), consisting of a portfolio of biogas power plants, a battery and a set of intermittent sources such as wind and solar. We operate under price and weather uncertainty and to handle it, we employ methods of machine learning. For price modelling, we consider the latest trends in the field and the most up-to-date events affecting the day-ahead and intra-day prices. We demonstrate the performance of the price models by both statistical methods and improvements in the profits of the virtual power plant. Optimization methods will take price and weather forecasts as input and conduct computer solving parallelization, decomposition, and splitting methods to handle sufficiently large numbers of biogas power plants and intermittent sources in a VPP. Finally, we demonstrate the positive social impact of such VPPs and the proposed strategies.
In this report, we explore the optimisation of virtual power plants (VPP), whose goal is to balance a wind park consisting of a portfolio of biogas power plants and a battery, while maximising the VPP revenues. Machine learning methods are employed to handle uncertainty in price and wind production. For price modeling, we consider the latest trends in the field and the most up-to-date events affecting the day-ahead and intra-day prices. The performance of our price models is demonstrated by both statistical methods and improvements in the profits of the virtual power plant.
Optimisation methods will take price and imbalance forecasts as input and conduct parallelisation,decomposition, and splitting methods to handle a sufficiently high number of assets of a VPP to operate the methods. The focus is on increasing the speed of computing optimal solutions to large-scale mixed-integer linear programming problems. The highest increase in computing speed enabled by our method. which we called Gradual Increase. is two orders of magnitude. Further progress in this methodology and its new facets are demonstrated.

The ALPQ field trial involved the preparation, execution, and interpretation of a mathematical model of a VPP which includes battery and biogas-fired assets as a simulation trial on the off-line version of the ALPQ VPP management system using historical data to feed the simulation. The mathematical modelling focused on managing the assets of the VPP so that the revenue they generate is maximised. The effects of optimising the operations of the VPP by applying the optimisations of weather forecasting to predictions of wind generated energy by a VPP, developed in WP3, is examined. The sensitivity of the level of revenue generated to changes in a range of input parameters to the model, including the parameter of varying the number, size and type of assets to be managed by the VPP, has been performed. The inclusion of battery storage and biogas-fired assets is specifically examined. The results of the modelling are expressed in terms of the level of revenue generated and the level of investment generated by the different versions of the model defined by varying the input parameters of the model regarding forecasting methods.
D5.3 Report on field trial of frequency inertial response and dynamic-phasor driven voltage control concepts in Italy
The deliverable describes the design, the development, and the operation of the Italian field trial. Instrument transformers and PMUs (commercial and prototypes) have been deployed in the live distribution network of Unareti, to collect measurements for the edgeFLEX edge control algorithms to be tested. The deliverable, though, is divided in two main sections. The first section focuses on the design and development of the trial. The second section presents the results of the application of the implemented edge algorithms.
The goal of the edgeFLEX SWW trial, located in Wunsiedel Germany, is to test and evaluate the edgeFLEX services supporting new concepts of power grid management and energy chain supply by enabling the use of local flexibility which could be traded on a local energy market. These services aim to provide support for the energy supply system both under normal operating conditions (slow dynamics), and for network system stability (fast dynamics). The testing has demonstrated that available local flexibility can be leveraged to overcome grid events such as over voltage, in addition to supporting energy supply by utilising the VPP and energy community, through using existing EMS, newly developed advanced edgePMUs and the edgeFLEX Platform components, services and interfaces.
An extensive range of tests of edgeFLEX services and enablers were undertaken in the live 5G networks of Ericsson in an indoor laboratory setting with a live 5G network transmitting at low power. The latency of the transmission was the main parameter tested on standard 5G networks and with advanced prototypes of the forthcoming URLLC 5G networks not yet available on the market. In addition, Ericsson’s 5G Device Management API proof-of-concept was integrated and tested with selected edgeFLEX platform components, and its features beneficial for DSOs and VPP operators were presented. The tests demonstrated that 5G can fulfil the requirements of the edgeFLEX services and enablers. Using the URLLC test infrastructure, latency was significantly reduced. Additionally, it was demonstrated that the 5G Device Management API improves the ease of use of 5G for power providers and security in data exchange between DSOs and VPP operators.
This document introduces the edgeFLEX approach to combine technological approaches with organizational structures in order to provide more flexibility in the European electrical network, at a moment when the need to mitigate fluctuation in power generation due to the increasing share of intermittent energies in the electrical mix in Europe becomes crucial. On the one hand are described the various technological solutions and sources of flexibility that can be relied on: they consist in central local flexible assets or distributed small flexible assets. On the other hand, are explored organizational structures can be used to foster the harvesting of flexibility; they may be DSO centered, aggregation-service-provider centered or happen thanks to local energy communities.

Both business scenarios are assessed and compared using the process. Finally, the report details the ongoing adoption of VPP2.0 within a real DSO and examines the barriers to adoption and the changes needed with in the DSO.
