In the issue of energy surplus, electricity surplus is clearly an important component. The introduction of new energy policies has accelerated the development of new energy in China. However, due to economic development and various factors, the power industry may experience more rare consumption than other energy sources. In terms of instrumentation, online monitoring systems can monitor the power system and grasp the details of power energy development. The application of online monitoring systems in the power industry can collect environmental data near power stations, achieve real-time monitoring and display of nearby data, and display results through big data. In the future, energy monitoring systems will enhance their applications, expand their monitoring scope, display data on energy development, and identify development challenges. At present, solving the problem of new energy consumption mainly involves three aspects. Firstly, strictly controlling the use of traditional energy in the instrumentation industry. Compared with new energy, traditional thermal power energy has advantages in terms of cost and utilization rate. However, instruments and meters are widely used in thermal power, which will inevitably cause the impact of thermal power energy on new energy and lead to more serious consumption of new energy. Under the premise of responding to energy supply side reforms, the dependence of energy on instruments and meters will increase. If instruments and meters for electricity can focus on the research and development of renewable energy, then the problem of energy consumption has already been solved by half.
