CAPSIM assists clients developing projects for connecting their energy production installations into the electrical transmission, distribution grid or into isolated networks (such mines, ports, etc…)
Whether they be wind farms, solar installations or biomass plants, the technical studies produced by CAPSIM guarantee compliance with the texts in force (regulatory texts, laws, grid codes, etc.) as well as the optimal sizing of the electricity grids within the facilities.
With its calculation tools, CAPSIM models facilities and produces all the justifying simulations and calculations: short-circuit current, voltage plan and reactive power compensation, harmonics, verification of the grid stability, FRT study (Fault Ride Through), optimisation of internal losses, etc.
CAPSIM has also analysed the case of the generator connections within industrial facilities, such as biomass power plants at paper mills. In this case, the analysis has a bearing not only on the interaction with the RPT (public electricity transmission grid) but also covers the impact on the existing grid: replacement of equipment, review of protection plans, modification of systems (filtering, reactive power compensation).
CAPSIM also assists its customers in the design of innovative generators such as, for example, tidal stream generators and in providing advance verification of compliance with regulatory requirements through a modelling and simulation approach. The consideration of the various constraints the connection at the moment of conception enables an optimised sizing of the system and eventually the realisation of the additional “grid services” valued by the network operator.
Regarding the integration of renewable energy sources into isolated electrical grids (fuel saving or hybridisation of the power station), a complete knowledge of the dynamical behaviour of conventional energy sources associated with R&D experiences allowed CAPSIM to obtain renewable energy penetration rates well above those admissible, and this helped to achieve the maximum possible profitability.
