Resumen

Este análisis examina la incorporación de una planta fotovoltaica (PV) de 33 MWp en un sistema eléctrico IEEE de 9 barras, con el propósito de determinar la generación mediante el uso de PowerFactory. El propósito es establecer cómo la generación renovable influye en el perfil de tensión, flujos de potencia del sistema. La PV está formada por 11 inversores y 6.400 paneles solares, enlazada a la barra 8, con una capacidad nominal de 21.01 MW y un flujo reactivo de 10.02 MVAr. Los valores de tensión se mantienen en el rango permitido (0.95–1.05 p.u.), con registros como 1.029 p.u. en Bus 5, 1.040 p.u. en Bus 9 y 1.039 p.u. en Bus 1. Los corredores críticos de transmisión se evidencian en los flujos más altos, que son entre Bus 4 y Bus 5 (-83.474 MW), así como entre Bus 6 y Bus 9 (-72.314 MW). La PV, en horas de sol, proporciona hasta 31.85 MW, lo que equivale al 8–9% del total; la generación convencional, por su parte (G1: 73.45 MW, G2: 163 MW y G3: 85 MW), contribuye con más del 90% de la energía. La fuente de corriente continua funciona como un sistema de almacenamiento, absorbiendo entre -10 MW y -33 MW. A pesar de que se necesita optimizar la gestión del almacenamiento, estos descubrimientos confirman que el sistema no se ve afectada por la integración fotovoltaica y que esta mejora la sostenibilidad.

Abstract

This analysis examines the integration of a 33 MWp photovoltaic (PV) plant into a nine-bus IEEE electrical system to determine generation using PowerFactory. The aim is to establish how renewable generation influences the system's voltage profile and power flows. The PV system consists of 11 inverters and 6,400 solar panels, connected to bus 8, with a nominal capacity of 21.01 MW and a reactive power flow of 10.02 MVAr. Voltage values ​​are maintained within the permissible range (0.95–1.05 p.u.), with readings such as 1.029 p.u. at Bus 5, 1.040 p.u. at Bus 9, and 1.039 p.u. at Bus 10.029 p.u. at Bus 11.029 p.u. at Bus 10.03 ... On Bus 1, critical transmission corridors are evident in the highest flows, between Bus 4 and Bus 5 (-83.474 MW), and between Bus 6 and Bus 9 (-72.314 MW). PV, during daylight hours, provides up to 31.85 MW, equivalent to 8–9% of the total; conventional generation (G1: 73.45 MW, G2: 163 MW, and G3: 85 MW) contributes over 90% of the energy. The DC source functions as a storage system, absorbing between -10 MW and -33 MW. Although storage management needs optimization, these findings confirm that the system is not negatively impacted by PV integration and that this integration improves sustainability.
