含电转气的电–气互联系统可靠性评估
Reliability Evaluation of Integrated Electrical and Natural-Gas System With Power-to-Gas
摘要
Abstract
Integrated electrical and natural-gas system with power-to-gas is an effective approach to solve the problem of abandoned wind power in the future. Its reliability evaluation is the basis of system planning and operation. Therefore, firstly, taking into accountthe phenomenon of wind power abandonment, this paper suggested an energy flow model based on power-to-gas device and gas turbine, plus an optimization model of electric/gas/heat load shedding considering abandoned wind power. Secondly, from the system and equipment perspective, this paper established reliability indexes such as expected electric/gas/heat demand not supplied, expected wind power abandoned and power-to-gas device capacity utilization. Then, based on the energy flow model and the optimization model of load shedding as well as the reliability indexes, this paper proposed a reliability evaluation method of the integrated electrical and natural-gas system with power-to-gas, considering the random factors of component failure, wind power and electric/gas/heat load. Finally, in different wind power penetration and capacity of power-to-gas device, the simulation results of IEEE14-NGS10 integrated electrical and natural-gas system verified the effectiveness of the proposed method.关键词
