Integrating distributed resources into the smart grid.
The remedy for America’s gravest economic woes may lie in a smart grid that can deliver vast amounts of clean, renewable energy while enhancing our energy security and democratizing our energy system. Although regulatory questions and technical challenges might dominate the industry’s short-term focus, the smart grid’s driving forces parallel America’s long-term national interests — a fact that should guide ongoing technology strategies and investment decisions.
Integrating renewables in New York.
New York has developed new market mechanisms intended to effectively incorporate large amounts of renewable energy in the future — up to six times the current levels of intermittent energy without impacting system reliability. New York ISO executive Rana Mukerji explains how the market will drive new investment in renewable energy in the state.
Large grids can integrate more wind—without major burdens.
Despite the variable nature of the resource, wind can be managed so that it will not impair the reliability of a utility system. The Federal Energy Regulatory Commission proposed a rule that would require changes to the way transmission service is scheduled, which would enhance the ability of balancing authorities to integrate wind.
Past accomplishments and future plans.
Policy makers in the E.U. and the United States are taking different approaches to facilitating smart grid development. While both regions are setting standards that the rest of the world likely will follow, they also face difficult challenges in resolving issues around cost recovery, customer engagement and workforce preparedness.
Advanced systems turn ‘event-driven’ binary schemes into hybrid hierarchical controls.
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.
Green energy mandates might overburden gas pipelines.
Market rules could evolve to compensate gas suppliers for pressurizing pipelines when needed on short notice. Enhanced ancillary services will require innovative strategies using line pack in interstate pipelines and stepped up communication among gas and electric market participants to preserve reliability objectives in gas and electric markets.
Are subsidies the best way to achieve smart grid goals?
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.
