“…Is there DSO-DSO cooperation for the organisation of the flexibility market? (Hadush and Meeus, 2018;Stanley et al, 2019) / First, flexibility of resources connected to the distribution level has multiple use cases, i.e. flexibility for the grids of network operators, for system balancing or for portfolio balancing of Balance Responsible Parties (BRPs).…”

“…To the extent that this can be solved, there will be less need for flexibility markets, but that is a discussion beyond the scope of this paper. A discussion of so-called nodal pricing for distribution grids can be found in the MIT Utility of the Future report (MIT Energy Initiative, 2016) and a discussion of how zonal pricing could be implemented at distribution level can be found in Hadush and Meeus (2018).…”

Flexibility markets: Q&A with project pioneers

Flexibility markets are recognised as a promising tool to make better use of existing distribution grids and thereby also reduce the need for grid investments. In this paper, we analyse four pioneering projects implementing flexibility markets: Piclo Flex, Enera, GOPACS and NODES. Based on a literature review, we develop a six-question framework and we then analyse the projects with that framework. The questions are: (1) Is the flexibility market integrated in the existing sequence of EU electricity markets; (2) Is the flexibility market operator a third party; (3) Are there reservation payments; (4) Are the products standardised; (5) Is there TSO-DSO cooperation for the organisation of the flexibility market; (6) Is there DSO-DSO cooperation for the organisation of the flexibility market. We find that all the considered flexibility markets are operated by a third party. All projects also engage with multiple DSOs in order to become the standardised platform provider. Important differences between the projects are the extent to which the flexibility markets are integrated into other markets, the use of reservation payments, the use of standardised products and the way TSO-DSO cooperation has been implemented.

“…Other papers are dedicated to analyze the combination of the effect of the two (DG and EVCS) and of their suitable management in the distribution grids operation and planning [22][23][24][25]. Few papers deal with the problems related both to the distribution and transmission grids, linked to the DG and EVCS [26,27].…”

New Dispatching Paradigm in Power Systems Including EV Charging Stations and Dispersed Generation: A Real Test Case

et al. 2020

Electric Vehicles (EVs) are becoming one of the main answers to the decarbonization of the transport sector and Renewable Energy Sources (RES) to the decarbonization of the electricity production sector. Nevertheless, their impact on the electric grids cannot be neglected. New paradigms for the management of the grids where they are connected, which are typically distribution grids in Medium Voltage (MV) and Low Voltage (LV), are necessary. A reform of dispatching rules, including the management of distribution grids and the resources there connected, is in progress in Europe. In this paper, a new paradigm linked to the design of reform is proposed and then tested, in reference to a real distribution grid, operated by the main Italian Distribution System Operator (DSO), e-distribuzione. First, in reference to suitable future scenarios of spread of RES-based power plants and EVs charging stations (EVCS), using Power Flow (PF) models, a check of the operation of the distribution grid, in reference to the usual rules of management, is made. Second, a new dispatching model, involving DSO and the resources connected to its grids, is tested, using an Optimal Power Flow (OPF) algorithm. Results show that the new paradigm of dispatching can effectively be useful for preventing some operation problems of the distribution grids.

“…The same approach could be exploited in the future also to foster the TSO-DSO (distribution system operator) operations, as discussed in Section 5.1. Regarding the current and expected growing interaction between TSO and DSO, see for instance [2][3][4].…”

Distributing Load Flow Computations Across System Operators Boundaries Using the Newton–Krylov–Schwarz Algorithm Implemented in PETSc

et al. 2018

The upward trends in renewable energy penetration, cross-border flow volatility and electricity actors’ proliferation pose new challenges in the power system management. Electricity and market operators need to increase collaboration, also in terms of more frequent and detailed system analyses, so as to ensure adequate levels of quality and security of supply. This work proposes a novel distributed load flow solver enabling for better cross border flow analysis and fulfilling possible data ownership and confidentiality arrangements in place among the actors. The model exploits an Inexact Newton Method, the Newton–Krylov–Schwarz method, available in the portable, extensible toolkit for scientific computation (PETSc) libraries. A case-study illustrates a real application of the model for the TSO–TSO (transmission system operator) cross-border operation, analyzing the specific policy context and proposing a test case for a coordinated power flow simulation. The results show the feasibility of performing the distributed calculation remotely, keeping the overall simulation times only a few times slower than locally.
