Abstract

In recent years, regenerative electric heating (REH) equipment has been gradually promoted on the agenda, which has better energy saving quality than ordinary electric heating. REH has good control performance and has important economic value in peak regulation and environmental protection due to the thermal storage unit. In this paper, a "Gas-REH" joint optimal operation model with the objective function of minimum total energy cost is established, which is based on the gas heating model and considers thermal comfort for users. An optimal operation method of group load for REH considering economic benefit is proposed. Finally, a typical example analysis is given by YALMIP platform and CPLEX software package in MATLAB, and the result shows that compared to existing gas heating methods, "Gas-REH" joint optimal operation model can effectively reduce the energy cost of residents. The proposed optimal operation method fully responds to the peak and valley electricity price, it can also realize economic operation and indirectly respond to the power grid peak load shifting at the same time.

住宅蓄热式电供热群负荷优化运行研究

近年来，蓄热式电加热(REH)设备逐渐被提上日程，它比普通电加热具有更好的节能质量。由于蓄热机组的存在，REH具有良好的控制性能，在调峰和环保方面具有重要的经济价值。本文以燃气供热模型为基础，考虑用户热舒适，建立了以总能源成本最小为目标函数的“燃气- reh”联合优化运行模型。提出了一种考虑经济效益的REH群负荷优化运行方法。最后，利用YALMIP平台和MATLAB中的CPLEX软件包进行典型算例分析，结果表明，与现有燃气采暖方式相比，“燃气- reh”联合优化运行模型能够有效降低居民的能源成本。所提出的最优运行方法既能充分响应峰谷电价，又能实现经济运行，同时又能间接响应电网的峰移负荷。
