Managing Power Grid Constraints Across Multiple Time Periods

A comprehensive analysis of state-wise ramping behaviour using hourly data for the year 2023 reveals that opposing ramp directions between states occurred in 30%-50% of time blocks, challenging the net national ramp and complicating system-level balancing. Despite these challenges, India possesses sufficient ramping capability, particularly from thermal generators, but lacks a mechanism to harmonise ramping efforts of generators across state as well as regions. The paper proposes a layered Security-Constrained Economic Dispatch (SCED) framework, which combines intra-state optimization with a national-level coupling layer to align state-level ramp vectors without disrupting existing contractual structures. The paper also includes the recommendations e.g. regulatory recognition of ramping, improved data transparency, and incentivisation of flexible generation to support integration of renewables reliably in a cost-effective manner. #Flexibility #Ramping #SCED #Integration #PowerSystem #States #India 🇮🇳 https://lnkd.in/guZnDnSz

Achieving GB Clean Power 2030 requires a new approach to system operation. IT systems, and the level of automation, are clearly at the heart of the Skipped Battery issue which has been covered in todays FT, https://lnkd.in/eQ6JgEMt But if we are to operate a system with minimal use of fossil fuels in 2030, there is a need for a deeper look at system operation, and the market tools at the control rooms disposal. For example, there are some clear inconsistencies in timings: ⏱ Settlement is managed in 30 min periods ⏱ Gate closure (at which market participants notify the ESO of their physical positions) is 1 hour before the delivery/settlement period ⏱CCGT plants typically require 3-4 hours notice to operate and will have minimum run times (several hours) and power output ⏱Batteries and other forms of storage can respond in seconds and to precise power output, but dispatch requires multi asset functions Given the time pressure to manage constraints and system balances, and the poor systems, it has been easier for the control room to schedule big CCGT plants in advance and run them over several settlement periods - this is costly, wastes renewable energy resource and creates a market barrier for smaller and more agile technologies and DSR. One response has been to suggest an even longer gate closure (3 or 4 hours) - which would make it easier to schedule CCGT plants but doesn't do anything to address the underlying problem and would be a backward step. Regen's Progressive Market reform paper suggests three main solutions: https://lnkd.in/e2SwAK3w 1) Enabling the control room to schedule storage and DSR (and in future low carbon dispatchable generation) in advance of gate closure, procured through forward flexibility markets/contracts. 2) Widening participation in the Balancing Mechanism, and making the much needed investment in IT system, data digitalisation and automation to support multi-asset and multi time period dispatch 3) As these solutions work - reducing the gate closure period and the settlement period There is also a case for a joint industry project to look at forecast accuracy and incentives to improve physical notification. By 2030, for day-to-day balancing and constraint management, we expect to see the utilisation of low carbon and fossil fuel assets flipped - with fossils only used when essential for system security. That's a key part of Clean Power 2030.
