The Challenge
Developing the energy markets of the future will be a key factor to overcome these new challenges and to integrate the increasing complexity of the electricity systems. It provides an elegant and more optimum alternative to grid and assets investments. However, including this complexity into the markets is not straightforward: keep the market efficient, scalable and transparent while having a growing number of actors; representing more accurately the grid constraints; considering local needs while keeping the market liquid, etc.
The Solution
N-SIDE, as a key actor in the Energy market and expert in advanced analytics, offers its market clearing tool to contribute to a better integration of electricity markets (Day-ahead, Intraday, Balancing, Reserve) at different dimensions:
- National market clearing – The algorithm clears efficiently a multi-zonal national market, including various types of orders and maximizing the social welfare achieved by each market session.
- Cross-border coupling – By the coupling of national markets at the European level. EUPHEMIA, developed by N-SIDE, is the official coupling algorithm for the European day-ahead markets, determining the spot prices and volumes for 25 countries.
- TSO-DSO Coordination – By the optimization of energy and ancillary service markets at the global and local levels. N-SIDE algorithms leverage the flexibilities of DERs (Distributed Energy Resources) and allows an optimal coordination between TSOs and DSOs.
N-SIDE is using different types of advanced analytics:

Develop cutting-edge optimization algorithms to solve large-scale (multi-countries), non-linear (complex network representation, complex market rules), non-Convex (complex market products) problems in a limited amount of time.
Predictive analytics
Forecast ancillary services needs for different timeframes and the associated bidding strategy.
Descriptive analytics
Represent in an accurate and tractable way the different grid constraints at the cross-border, transmission and distribution levels.
Network model
Auction management
Define different bidding approach: explicit or implicit bidding (price based control)
Market product model
Price determination
