Study On Indicator System And Method Of Regional Power Grid Operation Mode

With the rapid development of China's grid and smart grid construction, the establishment of the indicator system and method for evaluating the operation mode of the regional power grid scientifically has theoretical and practical significance for improving the economics, flexibility of grid operation under the premise of ensuring the safety and reliability of power grid.According to regional power grid characteristics and combined with the actual needs of the power sector, This paper give the indicator system of evaluating the operation mode of the regional power grid which contain Ratability, Power Quality, Economics, Short-circuit current, Operation complexity, and Maintenance mode feature. It achieves quantified with giving the calculation method, fuzzy membership function and the basic idea of AHP and getting the comprehensive evaluation which using data envelopment analysis and fuzzy comprehensive evaluation techniques and other methods of evaluation.At the end of the paper, an example of real transformer substation is simulated and the feasibility of this method is proved.
