Specialised services for simulation and prediction of the behavior of the electrical system

What is it?

Ingelectus offers specialised services for simulation and prediction of the behavior of the electrical system, having experience in Spain and Mexico with the NTS (Normativa Técnica de Supervisión) of REE and CENACE in Mexico. In particular, we highlight: Grid integration studies, Modelling and Simulation.

Grid Integration studies simulate, analyze and optimize the behaviour of new elements connected to the electrical network. We use PSSE, DigSilent and EMTP, among other software tools to run the electromechanical simulations. This process has three main objectives: 

  • Ensuring the compliance of renewable power plants of the Minimum Technical Requirements (MTRs) of the Grid Codes proposed by the Transmission System Operator. (TSO) or Distribution System Operator (DSO). RRE NTS or CENACE grid code. 
  • Analyzing the impact of new elements on the transmission and distribution networks. Especially in medium and small isolated electrical systems, where the impact of these elements can be quite significant.
  • Designing control elements of renewable energy plants such as power plant controllers (PPC).

Electrical devices modelling and simulation is a service that provides software models of actual power electronics based devices and power plant controls. This simulation is carried out by mimicking their behavior in standard electrical systems simulation software, such as PSS / E®, DIgSilent and Matlab / Simulink. With what objective? Thanks to this process we can provide a complete overview of the devices (PV, ESS, STATCOM, among others) and power plant controllers (PPC).

How does the modeling and simulation service work?

  • Models match the behaviour of electrical devices or power plant controllers. With this process we can use these models on standard electrical power systems software such as PSS/E® or DIgSilent.
  • Simulations in these software platforms with the custom models are the best approach to the actual behaviour during electromechanical events. With these simulations you can analyze and prove the compliance of Grid Code Requirements.

For whom?

From Ingelectus, the Grid Integration Studies process can help different professional profiles that work with the electricity grid routinely. We detail them below:

Professional Profile How can Ingelectus help?
Transmission System Operators We ensure that every MTR, we help you design new MTR according to global agreements and avoid possible integration problems.
Plant Promoters This service allows you to have the necessary knowledge to invest and minimize risks. It also allows you to ensure compliance with the minimum technical requirements imposed by the GRT or the DSO.
Plant Owners We guarantee the correct operation of your plant and help you design a proper power plant controller (PPC).
Manufacturer This service can be a fundamental and differentiating factor to make an offer. It allows you to show up that the devices meet every requirement.
Technical Advisors Grid Integration Studies could help you to make better analysis and therefore decisions on the object itself.
Operation and Maintenance We develop a proper power plant controller (PPC) and improve your knowledge about how the facility works and how it should be managed.
SCADA developers We help you to design a power plant controller (PPC)
