摘　　要：需求侧资源的灵活调节可促进本地分布式光伏电力的就地消纳。基于空调负荷的可调控性,本文以空调负荷为灵活性需求侧资源,提出与动态电价相适应的空调系统主动调控策略并对能源系统的优化运行进行分析。首先,设计了1个动态电价方案;另外,为提高需求侧电需求与光伏发电的匹配程度,在保证用户舒适度基础上结合室外环境温度变化规律,利用需求响应策略对空调负荷进行主动调控。其次,建立了能源系统中电源侧出力与需求侧负荷优化管理的协调运行模型,使用CPLEX求解器进行优化求解。最后,通过算例结果表明,当负荷曲线得到合理调控后,本地光伏的利用率有明显提升,建筑能源系统的日运行费用相应地也有明显降低。Flexible regulation of demand-side resources can facilitate the local consumption of locally distributed photovoltaic power.Based on the adjustability of air conditioning load,this paper took air conditioning load as the flexible demand-side resource,proposed an active regulation strategy for air conditioning system suitable for dynamic electricity price,and analyzed the optimal operation of the energy system.It first designed a dynamic tariff scheme.And to improve the matching of demand-side electricity demand with PV generation,the DR strategy was used to actively regulate the air conditioning load while ensuring customer comfort in combination with the outdoor ambient temperature change pattern.Then,a coordinated operation model for the optimal management of power-side output and demand-side load in the energy system was established,and the CPLEX solver was used to optimize the solution.The results show that the utilization of local PV is significantly improved and the daily operating costs of the building energy system are correspondingly reduced when the load profile is reasonably regulated.
