We analyse the dynamics of the energy system
anticipating challenges and opportunities
Key To Energy’s expertise in analysing the energy landscape emerges thanks to the in-depth activities and methodologies we adopt to assess the evolution of the energy system and the resulting impacts on operators. Our scenario-building process is based on the analysis of current policies, declining scenarios with market and grid models: this allows us to comprehensively analyse the dynamics of the energy system and anticipate the challenges and opportunities that operators will have to face.
We perform a detailed analysis of the short-term marginal costs of generation units, carefully assessing the cost profile captured by renewables in the electricity market: a perspective that allows us to gain an in-depth understanding of the economic dynamics and potential variations in generation costs.
In the context of the electricity system adequacy analysis, we adopt a probabilistic approach to assess the risks of non-supplied energy and define the minimum levels of generation resources needed to ensure sufficient regulation and reserve margins. We analyse resource requirements in order to supply storage and balancing in MSD (ancillary service market) and MB (balancing market), considering the contribution from the mix of available resources.
In addition, we examine the static security of the system under intact and contingency grid conditions – by means of the DC Load Flow calculation, we assess possible congestion on the grid at a level greater than 132 kV. For the purpose of quality and safety analysis on the nodes of the HV and EHV grids, we carry out a short circuit analysis, assess voltage profiles and the presence of intact grid constraints.
Finally, in order to simulate the stability of the system in a dynamic regime, we examine the Rate of Change of Frequency (ROCOF) and frequency transients in general following perturbations in isolated systems, thus contributing to a complete and accurate assessment of possible current and future criticalities in the energy system.
