摘要
需求响应对优化负荷分布、降低系统经济成本等方面的作用逐渐得到重视,为了满足用户的冷热电等综合能源需求,较多工业园区高峰时需从主网大量购电,不仅增加了园区自身运行成本,也加深了主网高峰时的调度压力。针对上述问题,以工业园区微能网系统为场景,考虑了热电耦合下的联合响应,以系统总运行成本最低为目标,最终形成工业园区综合能源协同调度策略。模型选取某智能园区一个典型日的用电情景进行优化,通过热电联合响应调整用户对不同形式能源的负荷曲线,实现能源优化配置。算例表明所提方法能够在峰时减少主网购电,增加园区内本地机组调用,并满足用户的冷热电需求,具备良好的经济性。
The role of demand response in optimizing load distribution and reducing system economic costs is gradually being emphasized.In order to meet users’comprehensive energy demand such as cooling,heating and power,many industrial parks need to purchase a large amount of electricity from the main network at peak time which not only increases the park itself operating costs also increases the scheduling pressure during the peak hours of the main network.In response to the problems,under the scenario of a industrial park micro-energy network system,with the goal of the lowest total operating cost of the system,a comprehensive energy coordinated dispatch strategy for the industrial park will be formed,considering the joint response under the coupling of heat and elec⁃tricity.This model selects a typical daily electricity consumption scenario in a smart park to optimize,and adjusts the user’s load curve for different forms of energy through the combined response of heat and power to achieve optimal energy allocation.The calculation example shows that the proposed method can reduce the main network power purchase during peak hours and increase the local generating units in the park meeting the needs of users for cooling,heating and electricity,which has good economic benefits.
