住宅热电联产系统最近已在日本各地引入，预计将越来越普及。在推动住宅热电联产系统采用的过程中，制造商和客户都想知道该装置的发电机的最佳容量，以及装置安装后，应使用什么调度策略来最大限度地降低客户满足其电力和热力需求的成本。在本文中，开发了混合整数非线性规划模型。目标是最大限度地降低配备有热电联产工厂、储罐和备用锅炉的特定住宅客户的能源系统年度成本。该模型报告了客户可以根据其电力和热力需求采用的最佳热电联产系统容量。使用该模型，对典型住宅建筑的经济最佳热电联产投资进行了调查。此外，还详细阐述了敏感性分析，以显示最佳解决方案如何因某些关键参数的变化而变化。此外，作为住宅热电联产系统的主要组成部分，对储罐的最佳尺寸进行了分析。
Residential CHP systems have been introduced around Japan recently, and expected to diffuse more and more. During the process of boosting the adoption of residential CHP systems, both manufacturers and customers are interested to know the optimal capacity of power generator for the unit, and once the unit has been installed, what dispatch strategy to use in order to minimize a customer’s cost of meeting its electricity and heat requirements. In this paper, a mixed integer nonlinear programming model has been developed. The objective is to minimize annual cost of the energy system for a given residential customer equipped with the CHP plant, combining with a storage tank and a back-up boiler. The model reports the optimal CHP system capacities that customers could employ given their electricity and thermal requirements. Using this model, an investigation was conducted of economically optimal CHP investment for a prototypical residential building. Furthermore, a sensitivity analysis was elaborated in order to show how the optimal solutions would vary due to changes of some key parameters. In addition, as a main component of residential CHP system, the optimal size of the storage tank was analyzed.
