Vietnam Electricity Group’s Ho Chi Minh City Power Corp. (EVNHCMC) deployed a distribution automation system that facilitates automatic—and very quick—fault detection and handling with a success rate of

Using voltage data down to the consumer level is essential for grid optimisation and operational flexibility in the new era of intermittent generation and fast-changing user demand. Power grids were designed

The U.S. transmission and distribution (T&D) network is reliable and well-maintained, but as renewable energy continues being added to the grid, and demand increases due to growing data center needs and the electrification of transportation and manufacturing processes, work is necessary to keep up with the changing times. The U.S. government understands the need for […]

Risks posed by geomagnetic disturbance (GMD) and electromagnetic pulse (EMP) events add challenges to an already complex power system environment. But they remain crucial to address. How prepared is the power grid to withstand these powerful natural and man-made disturbances? On the evening of May 10, grid operator PJM Interconnection activated a rare geomagnetic disturbance […]

The need for more reliability and resilience of power delivery, both in the U.S. and worldwide, has utilities and grid operators looking for solutions to the challenge of bolstering the electricity supply. Electric grid infrastructure, both in the U.S. and other parts of the world, needs an upgrade. Increased power demand from energy-intensive industries such […]

Facing unprecedented lead times and skyrocketing costs, the transformer supply chain crisis threatens the backbone of the electric power industry, driving urgent calls for increased manufacturing capacity and innovative solutions. Can the industry rise to the challenge? For several years now, the power sector has frantically raised the alarm about an impending transformer supply chain […]

An array of technologies, both thermal and renewable, are being used in the design of microgrids, supporting distributed power generation across several sectors. The use of microgrids to provide reliable power for critical infrastructure is growing, and these off-grid installations also are becoming more prevalent as part of commercial and industrial (C&I) enterprises and residential […]

In the U.S., regional transmission organizations (RTOs) and independent system operators (ISOs) are responsible for overseeing the reliable operation of the high-voltage transmission system within their respective regions. In other countries, transmission system operators (TSOs) perform similar roles. In most cases, the primary objectives of these entities are to ensure the reliable and efficient operation […]

As coal, gas, and nuclear plants are retired, and wind and solar resources are added to the power grid, stability can become a problem. Understanding the solutions that are available to help manage potential issues is important for decision-makers so they can select the best options for their system. Grid stability and system strength have […]

SAIDI (System Average Interruption Duration Index) and SAIFI (System Average Interruption Frequency Index) are widely used reliability indices that measure the performance of power distribution systems. SAIDI represents the total duration of interruptions for an average customer over a given time period, typically a year. It is calculated by taking the sum of all customer […]
