Smart Grid

Advanced distribution management systems (DMS) are providing unprecedented levels of control and efficiency. With greater knowledge about system loading and status, utilities can better make investment decisions—and operators will be better able to keep the lights on as the power system evolves.

Much has been said about the smart grid’s potential for transforming the utility business. But while the industry has focused on technology, process and organization, another factor—data—likely will prove to be a key transformational driver. Benefits for utilities and their customers depend on how effectively companies make use of a torrent of new and powerful data.

Smart grid is a global phenomenon, but different countries are taking different approaches—for different reasons. For instance, utilities in Europe are more focused on laying the foundation for distributed generation and microgrids, while the United States is more concerned about creating standards for interoperability and security. Understanding the differences can help decision makers deploy smart grid technology effectively and economically.

Now that wireless carriers are promoting their networks as a cost-effective communications platform for smart grid data, they face legitimate questions about fundamental performance issues. But if public networks turn out to be the better choice in many cases, utilities might have some explaining to do before state commissions.

The smart grid is poised for a tremendous rollout of new and revised technology standards in the next few years, but that’s just the beginning. IEEE Standards Association President Charlton Adams Jr. explains the objective of the intensifying smart grid standards effort is to address and satisfy the full gamut of economic, political and social goals related to the smart grid.

FERC has proposed that wholesale energy markets should subsidize load reductions with full LMP (locational marginal price), without deducting the customers’ retail savings. Such a policy could distort the market, and other solutions might achieve the same objectives more efficiently.

State utility regulators begin to question the benefits of smart grid technology, and customers take to the streets in public protests and demonstrations to oppose installation of smart meters.

Smart grid technology is bringing inanimate objects to life. In connecting nodes and equipping the system with distributed intelligence, the network is developing toward an environment that becomes quasi-biological over time. Such an organic system might defy deterministic ideas of planning and control.

Much is riding on successful smart-grid deployments. Experiences at several utilities demonstrate the costs and benefits of today’s automation technologies.

Making the business case for the smart grid is an important utility goal. It provides the justification for making or deferring required investments. Utilities might find it necessary to engage in a cycle of continuous strategic planning.
