Now, fossil energy is the main energy, while the extensive use of fossil fuels has brought the problem of source depletion and climate change. Seeking clean and sustainable energy sources has become an important challenge. People are paying more attention to new energy, such as solar, wind and other new energy because of the characteristics of renewable, clean and pollution-free. In the development process of new energy, the price is the key to energy competition. When the price of new energy and renewable energy is same to the conventional energy, energy placement could be completion in the market. The new energy price influenced by many factors, such as energy policy, technology. A scientific and rational energy development strategy will play an important role in energy revolution.In this paper, the problem of new energy development encountered such as technology, price, policy and so on, have been in-depth analysis. Based on the analysis results, the government has proposed some recommendations in policy perspective to promote new energy development in a reasonable and efficient way.The main contents include:(1) The output characteristic equation and the simulation of the wind power and solar photovoltaic are proposed. Due to the influence of the randomness and volatility of wind and solar sources, the output characteristics of the wind power and photovoltaic power are both randomness and volatility. We also analyzed the impact of the different access patterns of wind power, photovoltaic and distributed energy on the network planning, operation, protection, economic and other aspects.(2) Analyzing the average investment of the thermal power, wind power and photovoltaic power generation in long-term energy power generation through the levelized cost of energy. Studies have showed that unconsidering the policy of subsidies and other incentives, wind power projects has more obvious advantages than thermal power project. According to that, we should change the understanding about the inherent high cost of new energy. On this basis, through computational analysis, discusses the factors that influence the actual development of new energy power generated. At the presented state, the government should gradually reduce subsidies for new energy power plant, and strengthen support for smart grid construction, and it is more favorable to use new energy generation in electricity demand centers.(3) Analyzing the reasons of abandoned wind around all the world, through analysis of the reasons of abandoned wind power, indicating the nature of problem is the problem of power system capacity for wind power. In order to solve the problem of abandoned wind, it needs wind power business, lost distribution companies and electricity customers, including all aspects of the various stakeholders to work together.The abandoned wind power heating systems and wind combined storage system in China are be used to solve the problem of abandan wind power. According the analysed results, the abandoned wind power heating systemare is subject to by electricity-heat ratio. The system is profitability only when the ratio is between1-2, in a state of negative earning when the ratio is greater than2.The discount rate also has a great impact on the economic system, the lower the discount rate, the better the economy. For wind storage system has been jointly run economic analysis, focusing on the technical and economic analysis of different energy storage systems, flywheel energy storage system is better in economic than super-capacitor energy storage, superconducting magnetic energy storage.(4) We make some suggestions for the development of new energy in China based our current new energy policies, laws and regulatios. From the point of the government, the government should play a leading role, make use of the new energy and provide policies guarntees for the development of new energy. Such as new energy tariffs, subsidies, taxes, etc; from the market point, it should establish new markets and improve the energy consumption; from the point of view of resources, for the new energy resources should be assessment in an accurate way.(5) Investigating the current energy value models, the shadow price model, the marginal opportunity cost model, the present value of revenue models, the computable general equilibrium model. We proposed a new energy value model, this model includes environmental factors and spinning reserve factors suitable for new energy sources, the new energy model can determine the tariff and statesubsidies for the introduction of new energy policies to provide evidence. Taking wind power as an example, in consideration of environment values and spinning reserve the actual cost of the wind power. Wind power still has some benefits, under tbe current price of on-grid wind power.
