Big Data Management of Smart City Energy Conservation and Emission Reduction

Smart city is the inevitable direction of urban development. As an important part of healthy and green urban development, energy conservation and emission reduction are closely related to the sustainable development of the urban economy. Load identification technology is one of the core technical difficulties to be solved in realizing the overall layout planning of the smart power grid. Statistics show that with the information provided by the non-intrusive load monitoring system, the energy costs can be cut down by 10–15%. This chapter introduces the load identification methods mainly around three methods. Besides, smart grid construction is a necessary means of urban power consumption behavior management, energy conservation, and emission reduction implementation. It is a general trend to apply the construction technology of smart grid to smart city planning, which is conducive to the transparency of the intelligent target of distribution network and more guarantee of urban power supply. The implementation of smart grid technology helps to improve the overall operational efficiency of the distribution network, achieve the effect of all-around monitoring, and improve the quality of voltage acquisition. This chapter gives feasible suggestions from two aspects of urban power consumption behavior planning, energy conservation, and emission reduction efficiency, to promote urban smart grid construction.
