Estudios Eléctricos para conexión a Red de Renovables

Determining what happens when a renewable power plant is connected to the network is essential to the profitability of the project.

Due to the asynchronous, variable, and changing behavior of renewable technologies, the integration of these power plants into the grid faces challenges to power quality. Requirements such as the ability to continue to operate under fault conditions, low voltage (LVRT) or high voltage (HVRT) conditions; power factor, voltage control and reactive power requirements; limitations on harmonic emission, flicker, voltage unbalance or phase unbalance are some of the main concerns of electricity companies and network regulators.

We have a large team of professionals specialized in Technical Analysis and Power System Studies, supported by the most advanced and powerful modeling and simulation tools for diagnosis, proposal and validation of power quality solutions. In addition, a team of trained and qualified field technicians makes it possible for Arteche to take on-site measurements, which are basic for a detailed and complete analysis.

We develop power system studies in both static and dynamic state, simulating diverse and extensive scenarios; analysis and electrical diagnostics in Medium and High Voltage to obtain an accurate diagnosis of the installation and to provide solutions adapted to the needs of each project:

  • Power quality: Harmonics, flicker and voltage unbalance
  • Static power flow: Reactive power and power factor compensation
  • Dynamic power flows:  Voltage dips, LVRT, HVRT, P-f regulation, Q-V regulation
  • Electrical losses and voltage drop in installations 
  • Rapid voltage changes (RVC) 
  • Transients in dynamic regime (TRV): Switching studies
  • Short-circuit studies 
  • Reports on network status/Network code compliance

Arteche fulfills the complete package of studies required in Spain by the new Technical Supervision Standard (NTS). Performing these simulations and studies are an indispensable requirement for obtaining the Final Operational Notification (FON) and the Electricity Generation Module Certificate (MGE Certificate) according to EU Regulation 2016/631.
