Power Grid Model
The global energy transition is placing new and unprecedented demands on Distribution System Operators (DSOs). Alongside upgrades to grid capacity, processes such as digitization, capacity optimization, and congestion management are becoming vital for delivering reliable services.
Power Grid Model is an open source project from Linux Foundation Energy and provides a calculation engine that is increasingly essential for DSOs. It offers a standards-based foundation enabling real-time power systems analysis, simulations of electrical power grids, and sophisticated what-if analysis. In addition, it enables in-depth studies and analysis of the electrical power grid’s behavior and performance. This comprehensive model incorporates essential factors such as power generation capacity, electrical losses, voltage levels, power flows, and system stability.
Power Grid Model is currently being applied in a wide variety of use cases, including grid planning, expansion, reliability, and congestion studies. It can also help in analyzing the impact of renewable energy integration, assessing the effects of disturbances or faults, and developing strategies for grid control and optimization.
What to expect
For the upcoming meetup we are organizing, we have an exciting lineup of activities planned:
-Insightful presentations covering two practical applications of the Power Grid Model.
-An update on the latest advancements in Power Grid -Model technology during the first and second quarters of 2024.
-An interactive brainstorming session to discuss and propose new feature requests.
-An opportunity to connect with fellow Power Grid Model enthusiasts and users.

Power control for vast north sea offshore wind farm - Case Study
- 1. CASE STUDY Greater Gabbard Offshore Wind Farm is a huge offshore wind farm currently under construction in the North Sea 25 kilometres (22 miles) off the Suffolk coast. In the onshore substation for the site a total of three of Sollatek’s automatic voltage regulators control the power supply. The wind farm lies off the Suffolk coast and is located upon two sand banks, known as Inner Gabbard and The Galloper. When completed Greater Gabbard will be the world’s largest offshore wind farm with up to 140 turbines that can generate over 500 megawatts, enough to power 415,000 homes. Each turbine is mounted on a steel monopile that sits in water depths of between 24 and 34 m. There are two offshore substation platforms, housing electrical switchgear and transformers to step up the voltages from 33,000 volts to 132,000 volts. Three sub-sea cables will bring the power ashore to a new onshore substation located near Leiston in Suffolk, where it will be connected to the national grid via existing power lines. The Sizewell B nuclear power station is close by. Greater Gabbard is currently being developed by Scottish and Southern Energy (SSE) in a joint venture with the RWE npower renewables company. Offshore construction work is continuing and the development is on course for final completion in 2012. Sollatek (UK) Limited, Unit 10, Poyle 14 Newlands Drive, Poyle, Slough SL3 0DX. United Kingdom.

From small domestic (250 watt) to large industrial 500kVA applications, single and three phase applications, the Sollatek range of voltage regulators is your solution in the most erratic of power conditions. Case Study - AVR Gabbard Wind Farm April 2010 Artwork ID: 10910078 Stock No: 00039908 Source: SSE RWE, Installation of turbines SSE RWE, Energy Trading Centre Regulated power output Sollatek have supplied and commissioned three of its Automatic Voltage Regulators (AVRs) to provide a reliable, regulated supply to power the onshore substation’s control equipment and ancillary appliances. The new substation has three auxiliary 133,000 volts to 400 volts step down transformers connected to a three-phase Sollatek AVR3x600 voltage regulator, rated at 600 amps per phase. Only one of these auxiliary step-down transformers will be in operation at any one time, with the remaining two acting as switchable primary and secondary back ups. The Sollatek AVRs regulate the 400 volt three phase supply to the site’s LVAC distribution board. All Sollatek AVRs employ high performance solid state technology, which not only makes them ultra-fast at correcting voltage variations but also much less expensive than other stabiliser technologies, such as those that use mechanical systems. The compact design also means that they are virtually maintenance free and offer a longer operational lifetime. Leading technology By using microprocessor technology, Sollatek AVRs can rapidly detect voltage variations and correct the output to ensure a steady supply. They allow a very wide input range (from -30% to +22%of the nominal voltage level) and have a voltage correction speed of 1250 V per second. Sollatek are a world leader in the field of voltage regulation and protection, So wherever the electrical supply is erratic or unreliable, Sollatek has the ideal solution for protecting industrial, commercial or domestic installations.
