Cluster study
Document prepared by CENACE that contains the technical reports of reliability and, where appropriate, economic,
to determine the specific characteristics of the infrastructure required for the interconnection of a group of power plants,
load centers or the combination of both, with a capacity individual, equal to or greater than 20 MW and that together
have a capacity equal to or greater than 300 MW, located in the same geographical area with high renewable energy potential and
in the same area of influence, and which can be interconnected to the National Network of transmission
(RNT - "Red Nacional de Transmisión")
.
AEE - Analysis in stable state
Calculation of the operating conditions of the behavior of the National Electrical System (SEN - "Sistema Eléctrico Nacional") in
the generation of active and reactive power, active and reactive power flows in the electrical network,
angular openings, voltage profiles, etc., with all the elements of the electrical network in
service with application of n-1 contingencies for different generation dispatches
to identify overloads and reliability risks.
ET - Transient stability analysis
It will understand the behavior of the electrical system, by the integration of the power station
or the load center under study, to verify the angular and voltage behavior in the first oscillation,
interactions of protection schemes with power oscillations, dynamic deviations of the frequency,
damping of oscillations and in general the stability level of the SEN.
CE - Coordination of schemes
CENACE carries out the necessary studies to determine the adjustments that are required for
the correct coordination of the Remedial Action Schemes (EAR - "Esquemas de Acción Remedial")
and System Protection Scheme (EPS - "Esquemas de Protección de Sistema")
that are implemented and could be affected by the interconnection effect of a power station or
before the connection of a load center.
ECI - Estimation of Investment Costs
Analysis of the quality of the energy service (ACSE-"Análisis de Calidad del Servicio de la Energía"):
Evaluation of the quality of the electrical energy influenced by the harmonic content of current
and voltage, voltage variations and flicker rates, depressions or sags, surges (swells),
voltage and current imbalances, etc. by the connection of high-capacity non-linear loads,
such as fluctuating loads (electric arc furnaces, continuous arc welding machines, continuous saws,
etc.), impulsive and intermittent loads (induction motors, large cranes, punching machines, etc.).
distorting loads (induction furnaces, electrolytic tanks, large frequency variators, etc.) and
the interconnection of power plants of renewable, fluctuating, intermittent and distributed generation.
