Belgian PV GRID Workshop, Aprin 24th, 2014 - Namur
Date: April 24th , 2014
Time: 09:00 - 12:30
The national workshop was organised into the Walloon regulator offices. Edora decided to limit the amount of participant to be able have more time for interesting debates.
Edora made some bilateral meetings with ORES (DSO) before this workshop. The goal was to commit a bit more DSOs into PVGRID project in Belgium. We focused the event and managed it around them and their advices.
The discussions of the workshop were less focused on the technical questions as such, but more about the global framework that could pave the way of the introduction of such technologies.
The majority of the participants did agree to say that the main solutions are more or less technically mature. These solutions are at different levels of economic maturity, depending on their market penetration and market opportunity. As example, the inverter’s functions (P, Q and other control) are already available, but only need small design changes (e.g. command control) that could be ready within a few months (and not many years). Another example, concerning OLTC, the technology is considered mature by all, but the parameterisation and/or the way to program the algorithm is not yet ready and needs some time to direct the implementation of this technology within the system.
Therefore the real market opportunity is lacking, and should be addressed through:
- An incentive framework, ideally market oriented, meaning a specific market should be built;
- The proper modelisation of the grid, with the required algorithm to monitor and command the required devices (at MV and LV);
- A proper monitoring and management (control) scheme, with the right functions/parameters and way. This should be based on an efficient communication framework;
- An appropriate framework of interaction between DSO and TSO (e.g. the TSO grid code does not recognise the necessity to establish a strong relation between TSO and DSO. This missing piece is conducting to compromising the implementation of many solutions at all voltage levels)
- The appropriate grid code, in order to take into accounts the needs and requirements of all system’s actors.
The main discussions did address:
- The Business model of DSOs/TSOs (related to the efficiency of their investments on a global point of view)
- The necessity to create a new market framework for new business models to arise. These models would integrate progressively the technical suggestion of the PVGRID advisory paper.
