The construction of China’s extra high voltage (EHV) national electrical grid has ground to a halt due to the failure of the authorities to approve projects, hitting demand for copper wire and cable.

The first flexible alternating current transmission systems (FACTS), which mitigated voltage drops on the power grid, were deployed in the late 1920s.  Today, the rapid growth of large-scale renewable energy projects, which often supply intermittent power, is driving increased demand for FACTS. 

They found that connecting dead ends can significantly increase power grid stability. The findings are confirmed by a case study of the Scandinavian power system. Connecting dead ends increases power grid stability

The Swiss conglomerate ABB has solved the main technical hurdle to such grids. It has developed a practical high-voltage DC circuit breaker that disconnects parts of the grid that have a problem, allowing the rest to keep working.

These wonders of power electronics bring several benefits to the grid, including an improvement in the dynamic behavior of the system, increased load capabilities of the network and enhancement of the grid’s reliability.

Cables made from the new wire rod have much better characteristics.  Their durability and resistance to temperature is about 50% higher than normal ones have. Regarding the significant deterioration of the Russian power grids, new cables will benefit not only metals and cables producers but also grid and power companies.  RUSAL's product is also significantly cheaper than its US or European counterparts.  We expect this product will be able to partially supersede the expensive copper cables and broaden aluminium application limits”, commented UC RUSAL’s Technical Director Viktor Mann.

Survey conclusions, which are highlighted in a report titled “Power Systems of the Future: The Case for Energy Storage, Distributed Generation, and Microgrids” created by Zpryme Research & Consulting, include:
