No atual cenário de sistemas elétricos de potência, a Qualidade da Energia Elétrica (QEE) recebe cada vez mais notoriedade. Dentre os problemas de QEE, os Afundamentos Momentâneos de Tensão (AMTs) causam prejuízos financeiros consideráveis e localizar e mitigar as fontes de AMTs são um dos maiores desafios das concessionárias de energia elétrica. Nesse contexto, a tese proposta por (Passos, 2015) aborda um localizador o qual identifica de forma qualitativa (agente causador) a origem da fonte do AMT. Contudo, como sistemas elétricos de grande porte e malhados são mais complexos e com gradativo aumento de dispositivos não lineares, esse trabalho tem o encargo de avaliar tal localizador, através da modelagem de um sistema elétrico real de 92 barras e com a inserção de um compensador estático de reativos. Para tal estudo, a plataforma RTDS® (Real Time Digital Simulator) será requisitada para modelar o sistema.

An efficient power management control for microgrids with energy storage is presented in this paper. The proposed control scheme increases the reliability and resiliency of the microgrid based on three distributed energy resources (DERs), namely Photovoltaic (PV), battery, and diesel generator with local active loads. Coordination among the DERs with energy storage is essential for microgrid management. The system model and the control strategy were developed in Real Time Digital Simulator (RTDS). Decoupled d-q current control strategy is proposed and implemented for voltage source converters (VSCs) used to interface the PV and battery sources to the AC grid. A dc-dc buck converter with a maximum power point tracking function is implemented to maximize the intermittent energy generation from the PV array. A controller is proposed and employed for both grid connected and island modes of operation. In grid connected mode, the system frequency and voltage are regulated by the grid. During a fault in island mode, the diesel generator controls the system frequency and voltage in isochronous mode. Results based on the real time digital simulator are provided to verify the superiority and effectiveness of the proposed control scheme.

Steady State Performance

In this paper, a framework for integrating a real-time digital simulator and EMS-OPF program is proposed and addressed, through two different communication architectures: asynchronous and synchronous. Validation of these communication architectures is carried out by Ethernet UDP/IP (asynchronous) and analog channels of IO card (synchronous). With this framework, both dynamic and steady-state performance of a power system can be studied easily in real-time mode.
