考虑环境成本的火电厂负荷优化分配
Load optimal distribution for power plants with consideration of environmental costs
摘要
Abstract
Against the load optimal distribution problems in power plants after dedusting,desulfurization, and denitrification,a whole plant load distribution model considering environmental cost and a controllable exploration particle swarm optimization (PSO-CE)algorithm satisfying the real-time request of power dis-patching were proposed,from the aspect of improving the plant comprehensive economic benefit.The net coal consumption characteristic model and the multiple contaminants emission concentration characteristic model were constructed on the basis of the unit actual operating data.Then,the load distribution model for optimal comprehensive economic benefit and the self-adaptive load constraint condition were established, based on the dedusting,desulfurization,and denitrification compensation electricity price and the standard expense of pollutants emission.Moreover,the velocity factor of controllable random exploration and maxi-mum velocity limiting factor of dynamic adj ustment were introduced to the standard particle swarm optimi-zation algorithm to balance the computing cost and search ability.Simulations on the load distribution of a power plant with 4 units reveal the validity of the proposed method.关键词
