Análisis de energía firme en autogeneradores hidroeléctricos considerando la red de transmisión

Abstract

In this study a firm energy analysis on hydroelectrical self-generators is carried away, considering transmission network and establishing the technical criteria that will serve as reference for the formulation of the calculation methodology that self-generation project proposers should present in order to celebrate bilateral contracts with major consumers.

Firstly, using historical data available in statistical information reports from the electrical sector, an analysis of self-generators based on their energy production, self-consumption and energy surplus sales was conducted in order to know the actual situation in the studied self-generators.

Subsequently, a methodology proposal for calculation of firm energy for hydroelectric self-generators was developed, considering technical aspects as well the hydrological uncertainty for energy production from the sites; this methodology was developed with the aim to know the possible surplus of energy that a self-generator can make available for the electrical system.

The actual and future situation of the SNI was simulated, considering the planned activities in generation and transmission, the projection of demand, the system’s charge and the hydrology of the generation and self-generation centrals.

Based on the results obtained from the operative simulations, the reliability of the system’s energy supply was determined.

The simulations were developed in the SDDP software.
