Siemens Provides Solutions for Distributed Generation and Integrating Renewables into the Grid

The increasing demand for energy will need to be managed to a greater extent by renewable sources to protect the climate and conserve ever-scarcer natural energy resources. The Smart Grid enables smart generation by tapping into the potential of wind and solar power as well as geothermal energy, clean coal, energy storage and micro-turbine technologies. Successful integration of distributed and renewable generation relies heavily on effective planning and operation. The output of renewable generation (such as wind turbines or photovoltaic (PV) units) is highly intermittent with comparably few full-load hours, and it is difficult to predict. Siemens offers solutions for smart generation that make access to energy more dependable, consistent and sustainable.

 

Distributed Generation

The original electric grid was comprised of a series of local systems that were networked together. At the core of these systems were localized generation sources. As the systems evolved and electric supply became critical to the economic growth of the nation, a centralized model was embraced in America. This is the model seen today.

This model is under stress from a variety of forces:

  • Reliability is expected to be affected by aging baseload generation fleets, distribution systems and professionals who maintain these assets

  • Siting large-scale fossil fuel generation has become increasingly challenging

  • Renewable portfolio standards and greenhouse gas emissions regulations are increasing the need for renewable generation

  • Energy security and reliability concerns by large-scale and critical infrastructure customers are laying the groundwork for islanding capabilities

Though no single force is dominating the market today, the combination is creating increasing demand for distributed resources. The current focus in the market is on integrating renewable generation at utility scale to benefit the distribution system and the customer’s side of the meter.

They are distinguished from traditional utility-scale generation in that they enable a decentralized power network versus a linear power chain.

By taking an agnostic view of distributed generation and storage technologies, Siemens provides its customers with leading solutions at medium- and low-voltage levels to effectively employ and control smart generation assets safely and securely.
