Research On Low-carbon Benefits Assessment And Improvement Measures Of Power System In Henan Province

Energy and climate change are the most concerned issues by the world, and developed and developing countries are fully aware of the need to transform the economic growth mode, to promote environmental society and low carbon economy. However, the coal-dominated energy structure and primary energy as for oil and gas shortage in energy supply situation of the nation make the development of low-carbon economy and society facing great challenges, which resulting in a disadvantage position on international energy competition. While electricity occupies a central position in the energy strategy, and the low-carbon electricity industry development is a significant guarantee for achieving sustainable development and carbon dioxide emission reduction targets in China. Smart grid development, intelligent power system construction and low-carbon power technology’s greatly ripe, providing support for the large-scale renewable energy integrated in the power network and electric vehicles access. Moreover, transmission technology of higher voltage level highly improves the transmission efficiency, realizing indirect carbon emission reduction benefits. Furthermore, the implementation of demand side management, energy-saving devices and other measures can also achieve a significant energy saving benefits. The potential of low-carbon power sector development is huge.As one of the most large population province, Henan Province is transiting from the agriculture-based develop mode in the past to the industrialized urban construction. The province possess comprehensive energy types such as wind power, solar power, nuclear power, hydro power biomass power and other types of energy resources. At same time, in response to the national grid, the Province carries out energy services, and seeks for low-carbon development path. Based on this, Henan power grid low-carbon development potential is researched in the paper, low-carbon technologies and benefits of the power system generation side, transmission and distribution side, and demand side are analyzed, respectively. According to the assessment results, propositions are suggested, providing reference for other provinces power grid. Specific content includes the following aspects:(1) Current situation and development analysis of low-carbon power system in the nation and domestic. The part mainly reviewed the current development status of existing low-carbon technologies in the world, measures to promote energy services commercialization in developed countries, concentration of low carbon research in what areas, as well as the measures taken by foreign power grid in the low-carbon development, and energy conservation service process. The thesis provides a reference for the development of low-carbon power grid in China by taking Britain and the United States as inspiration.(2) The development path of low-carbon technologies of Henan power grid analysis. The section analyzed the species of low-carbon technologies and benefits in the generation side, transmission and distribution side and the demand side, provided specific assessment methods, and made empirical analysis of low-carbon technologies benefits in some links.(3) Research on benefit evaluation model of Henan power grid low-carbon development. The section established the low carbon benefit evaluation index system, with the system dynamics simulation software, the low-carbon benefits evaluation models of generation side, transmission and distribution side and the demand side (causal loop diagram, stack flow chart) was established. Besides, integrated carbon benefits of the system of each link were evaluated based on the system structural equation.(4) Improvement measures of the low-carbon development. Based on the research, suggestions promoting Henan power grid low-carbon development are proposed.
