Análisis Multi-Plataforma Para la Evaluación de la Emisión Armónica De Instalaciones Facts Tipo M-SSSC en la Subestación Santa Marta (Colombia)

Este documento presenta la metodología, análisis y resultados obtenidos al determinar, a través de simulación, el impacto en la distorsión armónica de la subestación Santa Marta, perteneciente al sistema de transmisión nacional colombiano, ante la futura instalación de dispositivos FACTS M-SSSC (Modular – Static Synchronous Series Compensator) para control de flujo de potencia. Utilizando una metodología multi-plataforma fue posible evaluar de forma integral la influencia que este tipo de tecnología tendría sobre el flujo armónico en la red de transmisión, considerando tanto mediciones reales de distorsión armónica existente en el punto de instalación, simulaciones EMT del área de influencia y validación del comportamiento del dispositivo utilizando un sistema RTDS para análisis en tiempo real. Los resultados permiten identificar que no solo los dispositivos FACTS considerados cuentan con una inmunidad suficiente a las condiciones existentes de distorsión en sitio, permitiendo una operación adecuada de control de flujo, sino que su emisión armónica y régimen operativos no representan un riesgo significativo de superar los límites de distorsión armónica de tensión establecidos para el sistema eléctrico, ni de generar interacciones armónicas perjudiciales con los activos del sistema en el area de interés del proyecto.

Power Flow Control Via Effective Dispatch of Modular FACTS Devices

A fast heuristic dispatch algorithm for series modular power flow control (M-PFC) devices is proposed to effectively control the power flow in transmission lines and consequently alleviate overloads in normal operation or contingency scenarios. Solving the nominal M-PFC dispatch problems is a computationally expensive non-linear program. Our fast heuristic dispatch algorithm leverages line outage distribution factors (LODFs) to model the impact of the M-PFC on the power flow change in the transmission lines, resulting in an iterative linear program that can be solved very quickly. Our proposed dispatch algorithm is assessed on three different test cases, IEEE 24 bus, IEEE 39 bus, and a real large-scale test case with 1723 buses. The numerical results support the effectiveness of the approach in terms of overload relief and its efficiency in terms of computation time. The proposed dispatch algorithm is applicable in both real-time operation and offline planning studies.

SSR Implication Assessment Using Modular FACTS

The increase of distributed, non-conventional generation requires fast installation and low-cost solutions that improve power systems’ flexibility and reliability. Such a solution is series compensation of transmission lines. Despite its numerous benefits, this solution raises concerns related to Subsynchronous Resonance (SSR). Flexible AC Transmission Systems (FACTS) devices constitute an improved alternative compared to traditional series compensation solutions

Technical, Regulatory and Economic Development for Distributed Flexible AC Transmission Systems – D-FACTS

This paper assesses the adoption of M-FACTS solutions (also referred to as DFACTS due to its distributed nature) from a technical, regulatory, and economic nature. This document covers the cost/benefit analysis and the regulatory point of view of DFACTS to explore the feasibility of applications in electrical power systems, starting from a perspectivewhere a wide variety of characteristics are analyzed. The intention is to favor the conception of a possible large-scale deployment of DFACTS in transmission systems, with innovative solutions to network restrictions and other relevant problems.
