摘要
为了满足用户对热能与电能的需求,解决现有多能源协调技术协调性能不佳的问题,提出考虑联合热电需求响应的多能源协调优化技术。综合光伏发电、风力发电、水力发电、燃气锅炉产热等能源生产方式,构建热电联合供给数学模型。在该模型下,根据用户的供暖面积和用电规律预测热电需求量,确定需求响应方式。利用能源枢纽装置实现能源之间的转换,调整能源波动峰值。在线路、购售电状态等条件的约束下,利用遗传算法求解数学模型,扩大能源存储容量,实现多能源协调优化。从实验结果中可以看出,该技术应用后,能够从热能和电能两个方面满足用户需求,有效降低能源消耗量,提高能源利用率,具有良好的协调性能。
In order to meet the requirements of users for thermal and electric energy and solve the problem of poor coordination performance of existing multi-energy coordination technologies,a multi energy coordination optimization technology considering the demand response of combined thermoelectricity is proposed.The mathematical model of combined heat and power supply is constructed by integrating energy production modes such as photovoltaic power generation,wind power generation,hydropower generation and gas-fired boiler heat generation.In this model,the thermal power demand is predicted according to the heating area and power consumption law of users,and the demand response mode is determined.The energy hub device is used to realize the conversion between energy and adjust the peak value of energy fluctuation.Under the constraints of lines,purchase and sale of electricity and other conditions,genetic algorithm is used to solve the mathematical model,expand the energy storage capacity and realize multi-energy coordinated optimization.It can be seen from the experimental results that after the application of this technol⁃ogy,it can meet the requirements of users from two aspects of thermal energy and electric energy,effectively reduce energy consump⁃tion,improve energy utilization,and have good coordination performance.
