At present, the prediction of the life cycle cost of fabricated substation is of great significance for the construction of fabricated substation. An enhanced prediction model based on quantum particle swarm optimization (QPSO) via least squares support vector machine is established. The relevant characteristic index of the life cycle of the fabricated substation is used as the input of the model, and the output is the life cycle cost. The simulation results are compared with the prediction results of QPSO optimized least squares support vector machine (LS-SVM), PSO optimized LS-SVM, traditional LS-SVM, and backpropagation neural network, which shows that the QPSO optimized LS-SVM model has better prediction accuracy, can predict and evaluate the life cycle cost more quickly, and can improve the benefits of fabricated substation construction.

This paper starts with the analysis of the characteristics of big data technology in the Internet era and its impact on the times, and then makes a thorough analysis of the problems faced by big data in the development process, including the requirements of high-level processing technicians, equipment, security problems in big data, and the problems of composition and governance. Then it elaborates in detail how to solve many problems faced by big data technology in the development in contemporary society. Starting from the needs of the times, China’s Internet technology has been developed and improved while improving the rapid development of big data technology.

The rapid prediction of the full life cycle cost of substation has guiding significance for the construction of substation. In this paper, a substation full life cycle cost prediction model based on advanced particle swarm optimization (advanced PSO, APSO) least squares support vector machine is established. The relevant characteristic index of the substation life cycle is used as the input of the model, and the output is the substation full life cycle cost. The simulation results are compared with the prediction results of APSO optimized LS-SVM, traditional LS-SVM, BP neural network four prediction models and related performance indicators. The simulation results show that the APSO optimized LS-SVM model has better prediction accuracy, and can predict and evaluate the life cycle cost quickly and accurately during substation design and construction, and improve the economics of substation construction.

Electricity market is gradually tending to be more energy-saving and environmental-friendly. In the context of medium and long-term electricity trading mechanisms, it is important to implement energy-saving and emission reduction with more reasonable and effective mechanism to solve the shortcomings in the overall environment and achieve energy conservation. The author finds that the core idea of energy conservation and emission reduction mechanism abroad to internalize the external cost. After in-depth study, the author summarizes the problems in realizing energy conservation and emission reduction in the medium and long-term electricity trading mechanism in the current market. The core design ideas and main development models of the mechanism are analyzed. Finally, the author analyses the design of market mechanism under the mode of trading volume restriction and power transfer in power plants. In the whole process, the author makes an auxiliary analysis with actual cases for peer exchange.

The energy crisis in the 21st century has become the most imperative problem to be solved by human beings. Nuclear energy is a vital base-charge power supply, which has high security, clean function and high efficiency. With the gradual development of nuclear power, the power is participating in the direct trading of the electricity market step by step. However, the rules of direct trading in China is not relatively complete, which leads to the unreasonable decline of the economy of nuclear power units. And there are drawbacks in the adjustment of energy structure, which also has a negative impact on energy conservation and emission reduction. So the author analyzes the current national nuclear power policies and electricity price costs, and proposes the current problems faced by nuclear power in direct electricity market and provides the basic directions and ideas for solving measures to help nuclear power better participate in direct electricity trading.
