“…A market design which gives consumers a wide array of choices concerning energy trading would become possible. As the data on the consumption and generation of electricity becomes accessible through the use of advanced metering schemes [44], consumer insight into the origin of their electricity use increases as well as a more accurate allocation and reconciliation process for the energy suppliers.…”

Several problems with stabilization of electricity grid system are related to the time lag between the electricity supply and demand of the end users. Many power plants run for a limited period of time to compensate for increased electricity demand during peak hours. The amount of CO2 generated by these power installations can be substantially reduced via the development of new demand side management strategies utilizing CO2 absorption units with a short start-up time.The sorbent can be discharged using radiofrequency (RF) heating to fill the night-time valley in electricity demand helping in the stabilization of electricity grid. Herein a concept of RF heated fixed bed reactor has been demonstrated to remove CO2 from a flue gas using a CaCO3 sorbent. A very stable and reproducible operation has been observed over twenty absorptiondesorption cycles. The application of RF heating significantly reduced the transition time required for temperature excursions between the absorption and desorption cycles. The effect of flow reversal during desorption on desorption time has been investigated. The desorption time was reduced by 1.5 times in the revered flow mode and the total duration of a single absorption-desorption cycle was reduced by 20%. A reactor model describing the reduced desorption time has been developed. 2 Highlights• An RF reactor system has been demonstrated for post-combustion carbon capture.• The transition time between the absorption and desorption cycles was reduced by 2 times as compared to conventional heating• The reverse CO2 desorption flow mode reduced the desorption time by 1.5 times.• The energy efficiency of RF heated and conventionally heated bench reactors was compared

“…The three curves in the figure correspond to three different post-fault steady state loading levels with the corresponding stable equilibrium points (δ) at 0, 30 and 60 degrees respectively. In [11] a vision of the smart grid from the market perspective was presented. In that vision, stability problems would be completely subdued to make the power grid as flexible as any other commodity network such as natural gas, water, railways, telecommunications and the internet as well as stock exchange.…”

Vision of a fail proof smart grid can be fulfilled using modern control capabilities. To maximize performance on the "edge", systems often evolve into a subtle mix of order and randomness (e.g., biology or astrophysics). Systems exploiting such "deterministic unpredictability" have been built (e.g., high performance aircraft).This paper proposes to expand the envelope of stable operations into the realm of "managed chaos" in order to realize an agile power grid that is more efficient and reliable with less redundancy in transmission capacity. This involves operation of the system with a string of local ephemeral equilibria created by changing control objectives, strategies and/or algorithms. The shallow potential wells around these equilibria keep the system prone to managed chaos, until reaching an acceptable final equilibrium. Overcoming grid stability problems as proposed would enable end-to-end direct transactions between energy producers and consumers with internet-like market reach, transparency and ease of execution.Index Terms-flexible smart grid, power and information market, relaxed stability, power system stability, power system reliability and control, fast local control, distributed autonomous intelligence, coordinated local and wide area control, ephemeral equilibrium.
