Energy Management System Technology in Smart Grid

The smart grid, envisioned as the future of the power industry, aims to revolutionize energy supply with efficiency and sustainability. This paper extensively examines the critical role of Energy Management System (EMS) technology within the smart grid framework. By harnessing advanced technologies like distributed energy storage, intelligent energy management, electric vehicle charging, intelligent energy dispatching, and fault perception diagnosis, the smart grid promises heightened power system efficiency, reliability, and environmental consciousness. In today's dynamic energy landscape, the integration of renewable sources introduces a unique challenge due to their inherent volatility. EMS emerges as the linchpin, offering real-time monitoring and data-driven optimization to ensure grid stability amid fluctuating supply. The smart grid, with advanced information technology and intelligent control strategies, leans heavily on EMS for seamless energy production, transmission, and consumption. However, challenges persist, encompassing stable energy supply, security, infrastructure upgrades, and cross-border standardization. Yet, with sustained technological innovation and collaborative efforts, a future of intelligent, sustainable, and reliable power systems is attainable. In conclusion, EMS integration into the smart grid not only signifies technological progress but also heralds a monumental shift towards a greener, more sustainable energy landscape. This paper provides a comprehensive exploration of how EMS, as the backbone of the smart grid, empowers us to navigate the complexities of modern energy demands, paving the way for a brighter, more efficient future.

Advanced Microgrid Energy Management System for Future Sustainable and Resilient Power Grid

Microgrid technology has found applications in various areas including institutional campuses, military bases, and remote islands. Many research efforts focus on the development of the microgrid steady-state energy management system (EMS) that can provide the day-ahead schedule or the multi-interval economic dispatch (ED) for distributed energy resources (DERs). This study advances the state-of-the-art microgrid EMS technique by developing a novel EMS approach to achieve a flexible time frame (FTF) DER schedule combined with a single time interval optimal power flow (OPF)-based ED. The FTF DER schedule enables the microgrid to fully utilize the latest updated renewable and load forecasts, and the OPF-based ED integrates realistic microgrid operating constraints in the real-time control. In addition, a mode switching control function is included to re-dispatch DERs in the microgrid for the planned microgrid switching from grid-connected mode to island mode. The feasibility and effectiveness of the proposed microgrid EMS technology are tested and demonstrated using modified IEEE 34-node and 123-node systems.

Energy management systems

This article examines some of the factors, trends, and requirements that will have the biggest impact on development of energy management systems in the next decade that are more reliable, secure and flexible, and capable of meeting the anticipated new requirements of pending legislation, deregulation, and open access. As the central nervous system of the power network, the control center - along with its energy management system (EMS) - is a critical component of the power system operational reliability picture. There is some ground to be gained by simply getting the EMS technology that is currently in use within the utility industry fully functional again to release the true potential value of the investment. EMSs should converge accurately and reliably under extreme voltage conditions, run fast enough to be useful in the time available, and be able to recommend remedial actions. Another key factor that is critical to the success of the EMS technology of tomorrow is the incorporation of advanced network analysis algorithms and applications. This presents not only a challenge, but also an opportunity to invest in new technology that will enable us to more effectively manage both the supply and demand side of the energy equation and is an equally important component to any long-term energy policy.
