Smart energy, smart grids – powering energy-intelligent societies


By 2035, more than 50% of electricity is expected to be generated by renewables worldwide. In parallel, electricity consumption is forecast to double by 2050.

Megatrends such as increasing urbanisation and climate change are driving the need for electrification and decarbonisation. Meanwhile, new applications in software and digitalisation are making grids smarter and more efficient, creating new business models. 

The growing share of electrical power generated from renewable energy sources is posing new challenges for power grids. Due to their intermittent nature, renewables can impact network stability and reliability. To protect critical components in power plants, such as electrical generators and step-up transformers, Siemens will introduce a new generator circuit-breaker to the market which features a compact design and a high level of flexibility to address customers’ challenges. To integrate the fluctuating infeed to power grids from photovoltaic (PV) systems, Siemens is offering intelligent infrastructure and storage technology such as its electrical Balance of Plant (eBoP) solution. 

A growing number of intelligent electrical devices are being equipped with the Internet of Things (IoT) interfaces, enabling them to exchange and analyse data while safeguarding secure communication. Siemens is also offering new grid diagnostic applications that collect and record data that until now were difficult for power grid operators to come by. This lends them the ability to gain useful insights into grid operations using analytics. In addition, Siemens will launch a new series of protective devices for high and medium-voltage grids, and industrial power networks.

Using efficient model data management and advanced analysis, Siemens can generate a digital twin of an electrical distribution grid within an entire IT landscape. The MindSphere Application Center for the Internet of Energy (IoE) will help transmission and distribution grid operators, utilities, industries and operators of buildings and infrastructures to analyse the collected data and develop strategies to increase productivity and profitability. This allows process optimisation and predictive maintenance planning. It also increases the energy efficiency of major power consumers while improving the reliability of the overall power grid. 

In the future, electromobility will increasingly contribute to a more efficient energy system. Siemens offers consulting services for e-mobility solutions aimed at integrating this sector into existing grids. Such efforts range from grid planning, grid connection, and development of business models to advising on the specification of hardware and software integration. Siemens will be presenting complete solutions for e-mobility charging infrastructure for urban applications such as depot charging for ebuses and e-service vehicles as well as public AC charging. These applications are highlighting the importance of battery storage as buffer and enabler for digital energy market integration. New products comprise the Sicharge CC AC22 charging station which is designed for public and semi-public charging environments and optimised for the use under any weather conditions without any additional enclosure. With its classic design it can be flexibly integrated into any existing infrastructure. The Sicharge UC family covers the entire power range from 50 to 600 kilowatts and facilitates fast and secure charging of electric buses, trucks and duty vehicles at the depot and en route.

By taking an holistic view about the application of energy across infrastructure, technologies can contribute to solve major challenges to tackle climate change, enabling the conservation of natural resources and supporting sustainable development by using energy more effectively.
