The challenge
Transmission networks are getting more complex. The shift towards more renewable energy poses new technological challenges – delivering power over greater distances from remote generation sites to major demand centers and managing supply-side variability. Transmission infrastructure investments have not kept pace with growth and, as a result, many transmission systems today are operating at or very close to capacity. How do you tackle these challenges while delivering consistently superior service to your customers? Network Manager can help.

Integrate seamlessly
EMS is the optimal control center solution to enable secure, efficient, and optimized operation of the electric power system. EMS has an open platform that allows for easy integration with other utility information systems while maintaining high levels of security. It is the market-leading platform for building control center solutions to manage today’s as well as tomorrow’s grids. Its modular architecture can be tailored to the needs of each company to provide a smooth migration path for future expansion.

The applications are built on an open platform, and can be tuned for real-time control and analysis as well as predictive optimization and planning purposes. These powerful network operation tools facilitate safe and efficient day-to-day operation while minimizing long-term capital expenditures.

Scale with ease
Each EMS function is implemented as a separate software package and interfaced with the system through a real-time database. This makes it easy to tailor the system to user requirements, to define execution sequences and cycles individually, and to add new software modules from Hitachi Energy or third-party suppliers as your system evolves.

Deploy with speed
We help you move from upgrades to updates with faster deployments. This can be tailored to a single-component level with cluster technology.

Up to date with international standards
As information exchange and coordination between transmission system operators (TSOs) and other market participants become more important, Network Manager is continuously updated to support international and local standards for power system operation and data-exchange. This is done by working closely together with customers worldwide and actively participating in the development of international standards.

Advanced capabilities

Advanced state estimation: Gain real-time information about network conditions, including power flows, voltages and phase angles, power losses, and more.

Volt/VAR Control (VVC): Minimize active and reactive power losses while keeping voltages within desired limits. 

Optimal power flow: Incorporate active grid elements such as HVDC, FACTS, and On-Load Tap Changers and more to reduce losses and enable sustainability.

Generation and demand forecasting: Leverage advanced machine learning to improve the accuracy and granularity of forecasts, which are critical for balancing supply and demand during economic optimization.

Open systems integration: Network Manager EMS easily integrates with other software, including systems used by external energy markets.

Dynamic Line Ratings (DLR): Use imported, forecasted DLR values in real-time and look-ahead studies to help integrate renewables and operate the system and equipment closer to their limits.

Stability analysis: Confirm whether your system is operating in a stable state by performing stability analysis calculations to assess the dynamic behavior of the system.

Security analysis: Network Manager EMS performs a series of power flow calculations to check various contingency scenarios and detect possible current or voltage violations.

Power flow analysis: Use the power flow engine combined with historical and future data, schedules, and forecasts to understand the state of your network and analyze different scenarios.

Wide Area Management System (WAMS): Monitor fast-developing power changes in real time by unlocking information from phasor measurement units (PMUs). Get more accurate analysis and insights into real time grid conditions by integrating WAMS with EMS/SCADA and operating with single data engineering and user interface.
