摘要
现有园区自动需求响应(automatic demand response, ADR)方法往往仅关注多种可控资源对于园区低碳调度的宏观指导意义,忽视了多种可控资源在园区低碳运行中低碳成本的准确计量,难以充分挖掘园区资源的调控潜能,导致碳排放量大、运行成本高等问题。为此,提出一种含多可控资源的低碳园区ADR优化方法。首先,对园区内空调、电动汽车、常规生产负荷3类可控资源进行建模;其次,以用电成本最低和空调室内温度舒适度最佳为目标,建立分时电价下的园区ADR模型;再次,通过飞狐优化(flying fox optimization, FFO)算法求解上述模型,获得最佳调控策略;最后,进行包含基础负荷、常规生产负荷、电动汽车、空调聚合商参与园区配电网调控的仿真测试。仿真结果表明,所提方法可使园区空调负荷的室内温度管理更加合理,电动汽车充电功率和常规生产负荷有效转移,不仅为低碳园区的碳计量成本提供指导意义,还能合理调控多种可控负荷使用,降低园区内综合用电成本。
The existing automatic demand response(ADR)methods usually only focus on the macro-guiding significance of various controllable resources for low-carbon scheduling in parks,ignoring the accurate measurement of low-carbon costs of various controllable resources in low-carbon operation of parks,which makes it difficult to fully excavate the regulatory potential of park resources and results in the problems of large carbon emission and high operation costs.Therefore,this paper proposes an ADR optimization method for low-carbon parks with multiple controllable resources.Firstly,three controllable resources in the park including air conditioning,electric vehicles(EVs)and conventional production load were modeled.Secondly,the park ADR model under time-of-use price was established with the goal of the lowest electricity cost and the best indoor temperature comfort.Thirdly,the flying fox optimization(FFO)algorithm was used to solve the above model to obtain the best control strategy.Finally,the simulation test involving base load,conventional production load,electric vehicle,air conditioning aggregator participating in the park distribution network regulation was carried out.The simulation results show that the proposed method can make the indoor temperature management of the air conditioning load in the park more reasonable,and the EV charging power and conventional production load transfer effectively.It not only provides certain guiding significance for the carbon metering cost of the low-carbon park,but also can reasonably regulate the use of various controllable loads and reduce the comprehensive electricity cost in the park.
