IBRs (solar PV, wind and BESS) are connected via inverters, which do not naturally respond to frequency. To provide grid support, inverters are programmed with frequency-power droop control. 𝗛𝗼𝘄 𝗱𝗿𝗼𝗼𝗽 𝘄𝗼𝗿𝗸𝘀 𝗶𝗻 𝗿𝗲𝗻𝗲𝘄𝗮𝗯𝗹𝗲𝘀:  • When frequency increases, the IBR reduces active power   • When frequency decreases, the IBR increases active power 𝗔𝘀 𝗽𝗲𝗿 𝗜𝗻𝗱𝗶𝗮𝗻 𝗚𝗿𝗶𝗱 𝗖𝗼𝗱𝗲 𝗖𝗘𝗔:  • All generating stations ≥ 10 MW (including wind/solar) must provide primary frequency response.  • Droop setting range: 3% to 6%  • Response time should be within few seconds If you want to deepen your understanding on PSCAD, join our ongoing course Insulation Coordination that started on 14.07.2025.

𝗛𝗮𝘃𝗲 𝘆𝗼𝘂 𝘀𝗲𝗲𝗻 𝘁𝗵𝗲 𝗳𝗹𝗼𝗮𝘁𝗶𝗻𝗴 𝘀𝗼𝗹𝗮𝗿 𝗽𝗵𝗼𝘁𝗼𝘃𝗼𝗹𝘁𝗮𝗶𝗰 (𝗣𝗩) 𝗶𝗻 𝗚𝗵𝗮𝗻𝗮? A 5-megawatt (MW) float PV power plant built on the Bui reservoir set the groundwork for regional emulation. Interestingly, this floating PV plant has been developed as an add-on to an existing 50 MWp ground-mount solar PV system, resulting in a total capacity of 55 MWp. Now, the exciting part is the deployment of a 30 MWh battery energy storage system (BESS) to help stabilize any intermittencies that will arise due to variations in solar power generation. "𝗜𝘁 𝗶𝘀 𝘁𝗵𝗲 𝗳𝗶𝗿𝘀𝘁 𝗼𝗳 𝗶𝘁𝘀 𝗸𝗶𝗻𝗱 𝗶𝗻 𝘁𝗵𝗲 𝗪𝗲𝘀𝘁 𝗔𝗳𝗿𝗶𝗰𝗮𝗻 𝘀𝘂𝗯-𝗿𝗲𝗴𝗶𝗼𝗻." 𝗕𝘂𝗶 𝗣𝗼𝘄𝗲𝗿 It is also worth noting that Bui has a 404 MW hydropower plant on site as well. Kudos to all who contributed in various ways to the development of these projects. 📈 Check here: Webinar shared ✅ https://lnkd.in/ebMXWmks Feel free to check my pages for more: ✅ Blog: shailearning.com ✅ YouTube: https://lnkd.in/efTZceP5

Major milestone for new electricity link between Scotland and England as EGL3 convertor station preferred bidder announced The Eastern Green Link 3 (EGL3) project – a joint venture between National Grid Electricity Transmission and SSEN Transmission – has named Hitachi Energy as the preferred bidder for converter stations at either end of the link. EGL3 will deliver 2GW of clean electricity – enough to power two million homes – through subsea and underground cables, helping to strengthen energy security in the UK and deliver on clean power targets. The announcement marks further progress on one of the UK’s biggest ever #electricitytransmission infrastructure projects. Hitachi Energy’s selection as preferred bidder follows a competitive procurement process and reflects the company’s strong track record in delivering #HVDC infrastructure both in the UK and around the world. The announcement of a preferred bidder does not influence or prejudge the outcome of any planning decisions related to the project. Mark Brackley national grid, Project Director for Eastern Green Link 3 at National Grid Electricity Transmission, said: We are pleased to confirm Hitachi Energy as preferred bidder for the EGL3 project’s converter stations. This is a major milestone for the project and another important step towards building the grid of the future. James Johnson, Deputy Project Director for Eastern Green Link 3 at SSEN Transmission, said: Reaching this milestone for EGL3 marks another significant step towards delivering the network reinforcements needed to unlock Scotland’s renewable energy potential. Once complete, EGL3 will form a vital part of the UK’s future electricity backbone – enabling clean, homegrown energy to flow where and when it’s needed and supporting energy security in the UK. Niklas Persson, Managing Director for Grid Integration Business at Hitachi Energy, said: With over a century of pioneering innovation, we are honored to be selected by SSEN Transmission and National Grid to supply HVDC technology for the EGL3 project. This will strengthen the UK’s interconnectivity and ensure a reliable, flexible, and affordable power supply. At Hitachi Energy, we are committed to advancing the UK’s energy system towards the Clean Power 2030 target. Armand Pineda, Senior Vice President, Head of Marketing & Sales for Grid Integration at Hitachi Energy, said:   We are honoured to be selected as the preferred bidder for the EGL3 project’s converter stations by SSEN Transmission and National Grid. This recognition reflects our long-standing partnerships with both major UK utilities and our shared commitment to delivering large-scale infrastructure that supports the grid of the future. Hitachi Energy is deeply committed to accelerating the global energy transition, and the UK stands as a flagship in this journey. https://lnkd.in/eM2tfcT8

🔍 Understanding the IV Curve in Solar PV Systems ⚡📉 The IV (Current-Voltage) Curve is a powerful diagnostic tool that represents the electrical behavior of a solar panel under specific conditions. It shows the relationship between output current (I) and voltage (V), helping assess performance, degradation, shading effects, and mismatch losses. 🔑 Key points: The shape of the IV curve reveals the health of a module. A flattened curve may indicate shading or cell damage. Maximum Power Point (MPP) lies at the “knee” of the curve — where current and voltage produce the highest power. Measured using IV curve tracers during commissioning, troubleshooting, or routine maintenance. IV Curve analysis is a vital part of solar PV testing & commissioning, enabling proactive maintenance and improved system performance. Don’t just install—analyze and optimize! 🌞🔧 #SolarPV #IVCurve #SolarTesting #Commissioning #PVPerformance #CleanEnergy #SolarMaintenance #RenewableEnergy #PoweringAfrica #SolarTraining #Photovoltaics #SDG7 #SolarTech #GreenEnergy #SolarInspection
