China proposed a development direction of “new infrastructure” in 2020, due to the ongoing scientific and technological revolution and industrial transformation. The charging station industry is one of the seven industries of the “new infrastructure”. Hence, it is of great importance to study China’s electric vehicle charging infrastructure industry. Based on game theory, this study analyzes the game strategies for the evolution of actors in China’s electric vehicle charging infrastructure industry. Firstly, the Chinese government has classified the industry according to the subsidy for charging piles and battery swapping stations. Then, the government, operators, and consumers constructed an evolutionary game model. The results show that: (1) under the investment subsidy mode, the purchase cost that consumers invest in purchasing traditional fuel-consuming vehicles has a positive impact on the operator’s production enthusiasm. In addition, the government’s subsidy amount has a positive impact on consumers’ decision to purchase battery-swappable electric vehicles; and (2) under the operational subsidy mode, due to the government’s strong supervision of the industry, there is a positive correlation between the word-of-mouth effect and the consumer’s decision to buy rechargeable electric vehicles.
Today the whole world is seeking to develop smart grid. Generation, transmission, distribution and power consumption have developments of different degrees in all countries. Therefore, researching on intelligent power consumption is an important trend to the smart grid. In this paper, the situation of intelligent power consumption is introduced in foreign countries; intelligent loads are classified in the intelligent power consumption; innovative modes of intelligent power consumption by mode conversion are proposed. In addition, the development of intelligent power consumption in our country is looked ahead.
Abstract. In recent years, in order to save line corridors and reduce the scope of demolition, some new transmission modes for high voltage AC and DC power transmission line are proposed. According to the characteristics of the parallel transmission line, this paper studies the distribution characteristics of the electric field intensity of multi circuit parallel transmission lines and the single circuit transmission line. Comparing and analysing the simulation results of the electric field strength, the safety measures for live working of 1000kV AC transmission line with multi circuit parallel transmission lines is put forward. That is the electric field protective equipment and measures used in the live line work of the 1000kV UHV AC single circuit line can meet the requirements of the live operation of the 1000kV UHV AC double circuit line.
