It’s not a surprise to me to see that someone (the AER in this case) has released an Issues Paper canvassing options for changing the way Semi-Scheduled generators interact with the dispatch process. Not a surprise, as our prior analysis suggests the current approach is not sustainable or scalable.
A brief note about the (also short) notice from the AER relating to two rule change proposals which it has been asked to propose by the COAG Energy Council
Tom Geiser, Senior Market Manager at Neoen, discusses the merits of proportional, relative control on the issue of small solar curtailment.
Recent invitations (from COAG Energy Council and AEMO) prompt some further analysis of the data set assembled for the GSD2019 in order to understand more about one of the challenges in balancing Supply and Demand in the NEM 2.0 world.
Our guest author Stephen Sproul looks at how the Dalrymple Battery Energy Storage System (BESS), currently the only source of virtual inertia on the NEM, responded to the November 2019 SA islanding event.
Guest author, Allan O’Neil tries to piece together further detail of what is intended with the apparent tightening of the Reliability Standard (which has sat at 0.002% USE for many years).
A back-dated article, looking back at the two ERM rule change requests which, when passed by the AEMC, had great effect in expanding transparency in the NEM in relation to generator availabilities from 20th August 2020.
Using the (hot off the press) Generator Statistical Digest 2019, we take a look across all 304 DUIDs to see how they performed through calendar 2019 in terms of large excesses in ‘Raw Off-Target’ in both directions. These results suggests implications for the future…
Two earlier articles today prompt this follow-on piece, specifically focusing on what’s being requested by ERM Power in two separate rule change requests relating to the MT PASA process.
Perhaps missed amongst all the bushfire-related action in the NEM, the SA Minister for Energy last week initiated the Retailer Reliability Obligation. Guest author Allan O’Neil tries to come to grips with what this means, and what happens next?
Guest author, Tom Geiser, discusses the different approaches to loss factors amid recent market proposals.
Guest author (and power system control specialist), Kate Summers, looks at what’s changed since she published a paper on frequency control in the NEM back in January 2017.
Better late than never (perhaps?) today I post a few thoughts about the AEMC’s proposed draft rule change for the incorporation of NegaWatts into centralized dispatch.
Some thoughts from Derek Chapman, from Adani Renewables, in conjunction with two rule change requests at the AEMC relating to Marginal Loss Factors.
Guest presenter, Kate Summers, spoke at UoM Climate and Energy College on 15th August 2018, with the presentation recorded. Kate shares this today with WattClarity readers.
A quick look back at the AEMC’s Final Determination on Five Minute Settlement.
A belated link to the Finkel Review.
The National Electricity Market (NEM) is designed to operate at 50 Hz. Frequency deviation occurs when generation and load are mismatched. It is important in a lightly meshed and long network such as the NEM to maintain tight frequency control and that frequency response is available throughout the network.
One of the most disruptive impacts on Australia’s electricity system over the past decade or so has been the rapid uptake of air conditioners – a consumer driven response to the introduction of inexpensive products from China.
It’s 18 months since the completion of the Smart Grid Smart City project – here’s some thoughts from one of the people who was very much involved in the project (a new guest author for us at WattClarity).
