Coordinated Scheduling, Dispatch and Control of Demand Response, Distributed Generation and Storage Resources

Emerging distributed and renewable sources of energy present challenges in operating power systems. At the distribution level, generalizing the functional model for balancing areas and adapting it to lower hierarchical levels of the distribution grid can address some of these challenges. Ubiquitous and inexpensive sensing, control and communication technologies allow the coordinated scheduling, dispatch and control of demand response, distributed energy resources and storage assets to address energy balance and phase balance issues in the distribution grid.

The Stabilizing Role of the Energy-Water Nexus

Electric power is required to produce, treat, distribute and recycle water while water is required to generate and consume electricity. While many potential challenges emerge from this energy-water nexus, a systematic and intelligent approach to simultaneously plan and operate power and water infrastructure can lead to stabilizing effects in both.

Conservation Voltage Reduction: Implementation and Assessment

There have been many successful experiences with CVR, but it still is viewed with some skepticism because of its somewhat uncertain and possibly negative effects on system operations. The ever-increasing penetration of distributed generation brings additional challenges. The main methods of CVR implementation and assessment are discussed.

Battery Swapping to Ease G2V and V2G Operations

The long idle time of electric vehicles (EVs) during charging and discharging does not comport well with future scenarios in which EVs play a big role. Though fast charging is a proposed solution to this problem, it has some drawbacks such as drawing excessive current and harming battery lifetime. Battery swapping is a promising solution.

About the Smart Grid Newsletter

A monthly publication, the IEEE Smart Grid Newsletter features practical and timely technical information and forward-looking commentary on smart grid developments and deployments around the world. Designed to foster greater understanding and collaboration between diverse stakeholders, the newsletter brings together experts, thought-leaders, and decision-makers to exchange information and discuss issues affecting the evolution of the smart grid.
