Study On Electricity Distribution Performance Evaluation Based On Data Envelopment Analysis

Electric energy is the most important and most widely used, the most convenient source of energy, and is the current world energy consumption one of the main forms. Along with the development of the national economy and the people's material and cultural living standard continues to improve, users of energy demand keeps rising, for increasing electricity demand of electricity supply reliability and quality have become increasingly demanding.Meanwhile, the distribution network dominance belonging to various companies under the non-independent accounting of all the power supply bureau. So during distribution network construction, its flow is Power's request for funds. According to the provincial network companies throughout the company plans to evaluate the project before distribution. Under such a system, all power supply bureau in order to seek to maximize their own benefits. It also calls for construction of distribution network for scientific assessment.However grid system and the scale of construction and operation efficiency and socio-economic research are less coordination. Now for the power grid is a network planning study, the main power grid construction to meet the technical requirements. The other network evaluation of the object is usually the macro and micro levels, that the macro through grid where electricity enterprise performance evaluation to completion of the evaluation grid system or micro level of network. The evaluation of the project to complete the grid system evaluation.This paper mainly based on the network level, the research network through the input-output characteristics, from the socio-economic and financial management are two internal perspective establish a more objective evaluation of the grid system, and using the data envelopment analysis to evaluate their relative effectiveness.Finally, this study evaluate the network depicts the state power grid itself, through data envelopment analysis to the public network efficiency and financial benefits of the combination of comprehensive evaluation, and this network enterprise network planning, enhance the competitiveness of enterprises is a certain significance.
