Abstract
In considering of high proportion of renewable energy supply in 2050, the accelerating of energy consumption gross, source and environment can affect the energy system restrict affection are stronger. Add wind and solar to electricity energy with large amount of energy source exploitation. The energy source amount per person is lower. Considering the renewable energy amount and supply, primary energy storage and structure problem is standing out. Before the wide spread of renewable energy, Using the high-carbon energy in China can pollute seriously. Chinese energy supply and demand problem is research key point. This paper researches Chinese energy supply and demand pattern system and evaluation methodology, gives out the inner and outer influencing elements. And evaluate Chinese energy supply and demand pattern from energy gross, structure, distribution and transportation. Use energy supply synthesize radar comparison chart in certain time period. From energy security, economy, clean and efficiency, analyze the benefit comparisons of Chinese energy supply and demand pattern. This energy supply and demand pattern model will give one certain theoretical analysis and practice reference to the further high proportion of renewable energy.
Highlights
Energy is the fundamental element of modern civilization
The main element analysis (PCA) include three steps, the first step is construct the covariance matrix according to the random vector
Considering all aspects of synthesize indexes historical development and further trend, making the equal synthesize indexes to scale in one degree, get the historical and further degree evaluation description
Summary
Energy is the fundamental element of modern civilization. From all countries development practice, the speed and degree of country and regional economic development is depending on modern energy supply guarantee system’s ability and construction. (2016) High Proportion Renewable Energy Supply and Demand Structure Model and Grid Impaction. Energy supply and demand is the key topic, confronting with new situation. (a) In China, until 2030, coal usage will be the fundamental electricity energy in long period of time, coal transportation and coal power layout optimization are much more impendency. Distribution energy sources are changing the world power configuration, affect the power grid structure. The renewable energy will be accelerated to the power generation energy supply. Energy consumption is approaching to the energy supply border It needs to layout Chinese power supply economically, stabilization, reliably under the global vision. Make the energy supply and demand structure as key line of current and future situations. (b) Evolution characteristics of our energy supply and demand pattern. (c) Research on the power grid function and affection to the energy supply and demand
