分布式电采暖负荷参与系统经济调度策略

ECONOMIC DISPATCH STRATEGY OF DISTRIBUTED ELECTRIC HEATING LOAD PARTICIPATION SYSTEM

电采暖是具有可时移特性的一种可调度负荷,但其数量多、容量小,集中式的调度方法已难以满足调度时效性,提出一种分布式电采暖负荷参与的电力系统经济调度策略,建立发电侧成本变化量关于发电侧出力变化量的函数关系式和电采暖负荷效益变化量关于用户电采暖负荷变化量的函数关系式。设计基于发电侧成本变化增量和电采暖负荷效益变化增量的多智能体主从一致性算法,求解经济调度问题获到最优经济的分配方案。通过实例仿真验证了调度策略的有效性。

Electric heating,a schedulable load with time-shifting characteristics,but it has the characteristics of large quantity and small capacity,which makes that centralized scheduling method is difficult to meet the timeliness of scheduling.An economic scheduling strategy of power system with distributed electric heating load participation is proposed.Firstly,the functional relationship between the variable quantity in power generation cost and in output on the power generation side and the functional relationship between the variable quantity in electric heating load benefit and in electric heating load of users are established.A multi-agent leader-follower consensus algorithm based on the incremental change of cost on the power generation side and the increment in the benefit of electric heating load is designed,which is used to solve the economic scheduling problem and obtain the economically optimal allocation plan.Finally,the validity of the dispatching strategy is verified by example simulation.
