The document discusses the increasing demand for electricity globally and the transition to renewable energy sources like wind and solar. This transition poses challenges for power grids due to the variable and uncertain output of renewables. Smart grid technologies like energy storage, demand response programs, and distributed generation can help balance supply and demand and make grids more flexible and adaptable to renewable energy. ABB provides many power and automation solutions to help utilities and customers manage this shift to more sustainable, low-carbon energy systems.

Electricity demand is calculated as the total gross electricity
generated less own use in the production of electricity and
transmission, and distribution losses.

more challenging given the volatility and uncertainty of wind and
solar energy sources

Properties of renewable generation
Challenging the power system
Variable and uncertain generation
Maximum output varies depending on wind and sunlight
No perfect forecast for wind and sunlight available
Inertial response capability
Non-synchronous generation technologies connect to grid via power
electronics and have little or no inertial response capability
Location constrained
Areas with the best resources are often situated in remote locations.
Tapping into these resources will require efficient ways to transport a large
amount of power over long distances.
Modularity
Renewable power generation can be found as residential or commercial
size. Increasing levels of distribution level generation will require new
approaches to regulate and manage this energy.

Enabling clean power for a sustainable world
Summary
 Large scale integration of renewable energy requires a
fundamentally new design of power systems
 Long distance transmission
 Integration of all types of highly distributed resources
 Matching highly volatile supply with demand
 Technological challenges
 HVDC overlay grids
 Storage
 Managing the complexity of millions of devices
 Stabilizing the system with little or no inertia
Many components are available already today, but may
need to be used differently than in the past
– some solutions still need to be developed.
