The Smart Grid is a series of interconnected, interoperable networks of control systems and asset‐management tools, empowered by sensors, communication pathways and information tools – all designed to help utilities deliver energy more efficiently to customers. Implementing the Smart Grid requires connecting existing utility grid infrastructure, in order to leverage legacy investments, as well as enabling future innovations with adaptable “future‐proof” investments in new Smart Grid technologies. Instead of focusing on single Smart Grid elements, the entire Smart Grid infrastructure of hardware, software and communications connectivity architected with the following underlying principles needs to be taken into consideration.
