As June’s extreme heat pushed PJM energy demand to the third- and fourth-highest all-time peak loads, PJM worked successfully with its generation and transmission owners to maintain the reliable flow of power to customers across 13 states and Washington, D.C. PJM coordinated reliable operations keeping fans and air conditioners on for 67 million people in its footprint amid conditions that stressed the grid at peaks over 160 GW – the highest peaks in 14 years. These efforts included extensive communications in advance and during the events Read more at PJM Inside Lines. https://lnkd.in/e6GduZTs

🌍⚡️ 𝐄𝐟𝐟𝐞𝐜𝐭𝐢𝐯𝐞𝐧𝐞𝐬𝐬 𝐨𝐟 𝐒𝐡𝐮𝐧𝐭 𝐅𝐀𝐂𝐓𝐒 𝐃𝐞𝐯𝐢𝐜𝐞𝐬 – A Key Insight for Grid Engineers! 🔌 Shunt FACTS devices like STATCOM and SVC control voltage by injecting or absorbing reactive power, without altering system impedance – they only respond to it, per IEEE Std 1031-2011 and IEC 61954:2011. 𝐖𝐡𝐲 𝐒𝐲𝐬𝐭𝐞𝐦 𝐒𝐭𝐫𝐞𝐧𝐠𝐭𝐡 𝐌𝐚𝐭𝐭𝐞𝐫𝐬 • Weak Bus Connection The same MVAR injection produces large voltage correction. Voltage regulation appears highly effective due to high voltage sensitivity. • Strong Bus Connection The same MVAR produces only small voltage change. Regulation seems weak because the system holds voltage stiffly. Conclusion: Effectiveness of shunt FACTS devices is inversely proportional to system strength – defined by short-circuit level (SCC), per IEC 60909-0:2016. In simple terms: • Weaker system → Higher voltage sensitivity → Better visible control • Stronger system → Lower voltage sensitivity → Limited visible control 𝐂𝐨𝐦𝐦𝐨𝐧 𝐌𝐢𝐬𝐜𝐨𝐧𝐜𝐞𝐩𝐭𝐢𝐨𝐧 Many assume shunt FACTS perform better in strong systems. This is incorrect. Strong systems already maintain voltage stability and respond minimally to reactive power, per CIGRE TB 78. Weak systems need support – that’s where STATCOM/SVC deliver maximum value. 𝐏𝐫𝐚𝐜𝐭𝐢𝐜𝐚𝐥 𝐈𝐦𝐩𝐥𝐢𝐜𝐚𝐭𝐢𝐨𝐧𝐬 This directly impacts: • Location Selection: Prioritize weak nodes for optimal performance. • MVAR Sizing: Avoid oversizing at strong buses. • Investment Decisions: Focus on voltage sensitivity studies. • Grid Code Compliance: Align with IEC 61000-3-6 and national codes. Installing a large STATCOM at a strong node may yield minimal improvement. The same device at a weak node can dramatically enhance voltage profile and stability. 𝐊𝐞𝐲 𝐓𝐚𝐤𝐞𝐚𝐰𝐚𝐲𝐬 • Short-circuit current defines system strength. • Voltage variation is higher in weak systems. • Shunt FACTS control voltage via reactive power. • Effectiveness increases as system strength reduces. • Proper placement matters more than device size. Understanding this principle ensures smarter deployment of FACTS technology in modern grids with growing renewables and variable loads. 💡 #FACTSDevices #STATCOM #SVC #GridStability #PowerSystems #SubstationDesign #SystemStudies

Unplanned transformer failures don’t just trip a breaker — they can halt production and burn through budget at up to $9,000 per minute in downtime. Our new white paper, “Reducing Manufacturing Downtime Through Proactive Transformer Monitoring,” shows how manufacturing leaders are using hydrogen-based transformer monitoring to: - Spot early warning signs before a failure - Turn real-time data into targeted maintenance actions - Align monitoring strategies with NFPA 70B - Protect uptime, shipments, and critical assets If keeping your plant running is non-negotiable, this is a must-read.
