Govt to introduce 17 islanding schemes for power supply

23 Aug 2021 CW Team

In addition to 26 existing and under-implementation projects, the government has revealed that it plans to implement 17 islanding schemes for power supply.

The islanding scheme is a power system defence mechanism that separates a portion of the system from a disrupted grid to help sub-part survive in isolation from the rest of the grid while maintaining supply to essential loads in that area.

This was cited in a ministry statement, according to the Central Electricity Authority (CEA).

All state load dispatch centres (SLDCs) have been instructed to create a separate islanding scheme display on their supervisory control and data acquisition (SCADA) systems for real-time monitoring of participating generators and critical loads, according to the CEA.

The CEA also mentioned that the same display would be available at RLDCs, SLDCs, and sub-SLDCs.

This will aid in the real-time monitoring of load generation balance on such electrical islands, which is critical to islanding success.

In this regard, the Delhi SLDC has taken the lead and developed a SCADA display page for generators as well as frequency-specific load relief information. This will be done for all of the country's islanding schemes.

These islanding schemes would ensure the maintenance of essential services as well as a faster restoration of electricity supply to consumers in the event of an outage.

With the CEA, all five regional power committees, Power Grid Corporation, and Power System Operation Corporation, Power Secretary Alok Kumar reviewed all existing and planned islanding schemes in the Indian power system.

The CEA was instructed to ensure that existing islanding schemes are functional and to design islanding schemes for major cities. Essential loads should be identified and covered in such an electrical islanded system so that they can be served even if there is a major outage.

India To Boost US LPG Imports, Cut Middle East Reliance

India is planning to reduce imports of liquefied petroleum gas (LPG) from the Middle East as state-owned refiners prepare to ramp up purchases from the United States, according to sources familiar with the matter. The move aligns with New Delhi’s efforts to expand energy cooperation and secure a broader trade deal with Washington. State refiners have already notified their traditional LPG suppliers in Saudi Arabia, the United Arab Emirates, Kuwait and Qatar of the potential reduction in imports. Although the exact size of the supply cut was not disclosed, earlier reports suggested that Indi..

UK Sanctions Nayara Energy in Crackdown on Russian Oil

The United Kingdom has announced fresh sanctions on 90 entities, including Indian refiner Nayara Energy Limited, in its latest bid to curb Russian oil revenues and weaken President Vladimir Putin’s war funding. The sanctions, unveiled jointly by the Foreign, Commonwealth and Development Office (FCDO) and the UK Treasury, aim to disrupt networks supporting Moscow’s crude exports amid the ongoing war in Ukraine. According to the FCDO, the new restrictions are intended to “strike at the heart of Putin’s war funding” by targeting firms and assets that enable Russia’s energy trade. “..
