Wind, solar farms to be blackened for up to 100 days because of a grid change


Printing, PDF & Email

Wind and solar farms in north-west Victoria and south-west South Wales have been warned up to 100 days or more in the following year because of the need for local distribution and distribution networks. refresh.

The warning from the Australian Market Operator will impact on wind and solar farms as north as Broken Hill in the west of NSW, and new and customary mid-Victorian projects. Responsibilities have already begun in some cases.

Most of the wind and solar farms are based on “rombus of regret”, part of the electricity supply which connects Mildura, Horsham, Kerang, Ballarat and Bendigo who are struggling to deal with the increase. T in regeneration. energy power.

Wind and solar farms affected by the Silverton windfarm are located at Broken Hill, with Broken Hill solar farm adjacent. In Victoria, the recently opened solar farms Wemen, Karadoc, Gannawarra and Bannerton have an impact on the opening of some of the former states, such as the Waubra, Crowlands and Kiata wind farms.

They seem to be the worst affected by solar farms Wemen, Karadoc and Broken Hill, who have been warned that they will be limited to production levels for a long time, and almost t all the work that is done over the next 13 months.

These works will be carried out on the various 220kV lines which connect the Red Rocks, Horsham, Wemen, Crowlands, and Kerang. The greatest impact will be from upgrading the communications infrastructure, with the wind and solar weeds being warned up to 76 tours, each lasting half a day to a full day. The timetable is still not in place and at least may be adjusted.

A further 24 full-time rounds will be required in order to upgrade the size of a line and a director, and there will be several more times to connect new wind farms such as Bungala Neoen and Trara Warra to the grid. The Murray Link link will also be affected to South Australia.

AEMO says that 480MW of wind and sun have been added to the graph in the past year, and with a further 900MW of generation expected over the next six months, this will continue until around 1500 MW. of a new generation in a truly lightweight transmission network.

As a result, a number of improvements will be required in the next six months on around 120 visits. This effect is that many generators in the region will be restricted, often to zero, during these visits.

Other resources can be downloaded to less than 5MW output, to ensure security of system through updating. (see below for an example).

One part of the planned cuts to AEMO.
  • One mentioned that the “situation is a surprise” but he admits that it should not be because it was in the table of network streams created by Ausnet, which runs the local network. .

    Among those taking part will be a CUB powerhouse, which derives from the 90MW Karadoc solar farm which is owned by Bay-Wa as part of its aim to get the same electricity needs from the sun.

    The 88MW Wemen solar farm, developed by Wirsol, is providing Simec Energy. Bannerton sun farm, with the UK Foresight Group, has a contract to power the trauma network in Melbourne.

    “Unfortunately little can be done – the work has to go ahead,” said the user.

    However, it contributes to the bodily bodies on the area of ​​wind and solar farms in the area, many of which are abandoned by releasing “causes of marginal loss”, which governs what is contained in the plan. the results of credit for payment.

    Some solar and wind farms – especially those at Broken Hill – have suffered a scale of over 20 per cent because of the higher density of the grid, and the distance from a mouse. Others have breached more than 10 per cent.

    On top of that, and RenewEconomy's last year, warnings about wind and solar farms in the area were warned before due to a lack of capacity on that part of the grid. This has the potential to influence the Victoria target of 50% of renewables by 2030.

    Some projects, such as the great Kiamal countryside, have decided to have synchronous conduits to resolve some of their cases.

    AEMO, in his explanatory memorandum, states that there is a need for a divide, as the local nature of change has changed so significantly in the past few years, with 480MW tied up in the 2018 area. All inclusive.

    “This has changed significantly the opportunity for short-term stays and existing levels with impact affecting voltage foundation behavior in this area of ​​the network,” he wrote. “The system is very different since a major disaster happened in the area.” T

    He says that he's looking at options to reduce their anxiety, such as putting on so much night work, so that there is no disruption to sun farms.

    AEMO says that the communications infrastructure needs to be installed because it is now possible. It proposes, as part of its Integrated System Plan, to further develop the area's network and add new lines to alleviate its density and bring in some 5,000MW of wind and solar projects. an area seeking grid connection. t
