将分枝界定、动态规划与序列二次规划法相结合,提出了考虑可选设备容量不连续性、设备最大最小出力限制、温度和出力对设备性能影响的带蓄能装置的分布式热电冷三联产系统(联产系统)优化配置问题的求解方法。以北京市某办公楼为对象进行了算例分析研究,验证了模型及其求解方法的有效性。计算结果表明,在北京地区发展联产系统具有较好的经济效益。在分时电价体系下,带蓄能装置可有效降低联产系统运行成本。
Integrating the branch specification method and the dynamic planning method together with the sequential secondary planning method,a solution method of optimized allocation problem for the distributed heat-electricity-cool co-generation system with energy-accumulating facility,which has considered the discontinuity of selectable equipment capacity,the maximum and minimum out-put capacity of equipment,and the influence of temperature and output capacity upon the performance of equipment,has been put forward.Taking one office building in Beijing as an object in calculation,analysis and study have been carried out,verifying the effectiveness of model and its method of seeking solutions.Results of calculation show that the development of co-generation system in Beijing area has comparatively better economic benefits.Under the system of power price according to time division,the triple co-generation system with energy-accumulating facility can effectively reduce the operating cost.
