In 2005, Campbell invented a technology using principles of group behavior (Swarm) so that electrical appliances in a building could coordinate and the power consumption in the building at peak times would be reduced. Campbell invented a wireless controller to connect electrical appliances in the building so as to achieve effective control. Running an air-conditioner for 15 minutes, for example, could maintain the indoor temperature at 24℃while the other two air-conditioners could stop for 15 minutes provided that the temperature remained unchanged. As such, the energy conservation goals of the building could be achieved without individual sacrifice. This technology made electrical appliances smart and enhances energy utilization efficiency.

The energy green paper published by the European Council in 2006, A European Strategy for Sustainable, Competitive and Secure Energy, stressed that smart grid technologies would play a critical role in guaranteeing the power quality of EU grids and point to the direction of grid development. The smart grid at that time probably referred to the automation technologies used in the transmission and distribution process.

In mid-2006, a company named Grid Point began to sell an electronic product that can be used to monitor consumption of household circuits and adjust power consumption of household appliances via network communications technology. This product has some interaction features, so it can be deemed as part of the smart grid infrastructure.

Also in 2006, IBM, a multinational computer technology and IT consulting corporation based in the United States, developed a solution of “smart grid” in cooperation with global power professional institutes and power companies. The solution was vividly called the “central nervous system” of power systems. Power companies could use sensors, meters, digital control equipment and analysis tools to automatically monitor grids, optimize grid performance, prevent power outages and restore power supply faster while consumers’ management of power consumption can also be allocated to each device connected to the grid. This can be seen as the most complete solution for smart grid and marks the official birth of the smart grid concept.

East China Grid officially launched the smart grid feasibility study project in October 2007 and planned a “three-step development” strategy lasting from 2008 to 2030, namely: the initial construction of an advanced dispatch center would be completed in 2010, the construction of digital grid with preliminary smart features would be completed in 2020, and self-healing smart grid would be built in 2030. The launch is a sign of China’s entry into the smart grid.

Boulder in Colorado, the United States, became the first smart-grid city in America in 2008, where every household is equipped with a smart meter and people can directly know the electricity price at the time so that they can arrange things like laundry and ironing when the price is lower. The meter can also help people first use clean energies such as wind power and solar power. Meanwhile, substations will collect information about power consumption of each household. Electricity will be redistributed once there is any problem.

The White House announced in its latest report of recovery package on January 25, 2009 that the United States would lay or update 3,000 miles transmission lines and install smart meters for 40 million American families—the US would promote an overall revolution of interactive power grid. Wu Jiandong, a Chinese energy expert, clearly stated in his article, Pushing Forward the Interactive Grid Revolution to Promote Economic Innovation and Transformation, that China’s grids badly needed a revolutionary transformation like the implementation of “interactive grid”.

On February 10, 2009, Google said it had started testing power consumption monitoring software called Google PowerMeter, an online meter in testing, which means that Google is becoming a public utility of the information age.

On February 28, 2009, the steady-dynamic-transient security defense and power generation control system of North China Grid, a part of the construction of smart grid in North China Grid, passed the examination by the panel in Beijing. The system integrated the once separate energy management system, wide-area real-time dynamic security monitoring system and on-line security and stability analysis and forewarning system so that people responsible for dispatching can achieve panoramic monitoring of the overall operation of the grid and obtain aided decision-making support without frequent changes between different systems and platforms. In addition, the system can effectively increase the level of standardization and process of grid-connected power plant management by dispatching departments through building a platform for grid-connected power plant management evaluation and aided service market quality analysis.

On March 3, 2009, Google, a search giant based in the US, advised the US Congress to adopt non-monopolistic standards in building the “Smart Grid”.

On January 12, 2010, the State Grid Corporation of China formulated the Opinions on Speeding up Construction of Strong & Smart Grid, in which it put forward the principles and overall objectives of developing Strong & Smart Grid.
