We help our clients better understand their systems and help them improve the performance of the grid.

The evolution of the electric power industry, both in terms of technology and restructuring, has impacted the goals, scope, and methods of power system simulation, analytical, and planning activities. Relatively new technologies, such as wind generation and distributed energy resources, do not always fit well into the standard analytical frameworks employed for assuring reliable performance of the power system. Also, the introduction and maturation of competitive power markets has altered the traditional equation for power generation, transmission, and distribution. These developments present both a challenge and an opportunity for electric power utilities, system operators, and customers in ensuring power system reliability, security, and efficiency.

EnerNex is involved in the ongoing grid modernization efforts in California and other states and for various utilities. Our involvement is on the architectural level as well as on the analytical level, utilizing the latest advanced analytical tools for modeling and simulation. This combination of knowledge and skills sets us apart from other engineering consulting firms, and provides our clients with comprehensive cutting-edge guidance that is so critical to these fundamental changes in the power industry.

Transmission and Distribution Studies
Power system modeling assists our clients in understanding what did happen, what may happen, or how to solve a potential problem. EMTP-RV and other simulations allow for an understanding of transients, harmonics and power flow issues. Our power system modeling and simulation capability covers the range of technical phenomena and issues important for highly-reliable power system design and operations.

We develop models and generate results using a variety of programs utilized by our clients.

Switching studies evaluate breaker transient recovery voltage, transformer energization, or ferroresonance concerns. Harmonic studies evaluate potential resonance and interconnection concerns with power systems.

Bulk Power System Analysis
Bulk Power System Analysis helps to evaluate the impacts of large-scale generation facilities on bulk transmission system operations, including steady-state and contingency analysis, impacts on interregional power transfer capability, network voltage stability, reactive power requirements and transient stability. One of our key areas of specialization includes the unique characteristics and impacts of wind plants and other intermittent generation resources.

Recent projects have included research into the utilization of synchrophasors and other advanced tools to prevent wide area blackouts. Evaluation and prediction of system phase angle differences can be used to predict instability and to initiation load shedding or controlled system separation. Synchrophasors can also be used to validate models and to understand the dynamic interactions of wind and solar plants on power systems.

Power Quality/Power Disturbance Troubleshooting
Garland Solar facilityWe perform a wide range of studies, ranging from site audits to extensive power system modeling and analysis studies involving simulation tools and monitoring regimes. Key areas of specialty include harmonics, transient and switching events, and voltage sags and flicker.

We have studied equipment failures, harmonics, and reliability concerns for banking, cable, and telecom data centers:

  • Evaluated harmonics in cell phone installations
  • Evaluated load pickup on generators in larger server data center
  • Evaluated equipment failures in steel and automotive plants
