摘要

提出一种考虑需求响应的热电联产(CHP)系统优化配置方法,科学合理地配置附加热源参数,降低不必要的投资和建设成本。首先,利用附加热源和需求响应将发电和供热解耦,提高热电联产系统的灵活性。其次,以系统综合满意度、经济成本和风电消纳能力为目标,以机组出力和附加热源容量参数为决策变量,建立了热电联产系统的多目标优化配置模型。此外,还设计了一种改进的记忆算法(IMA),结合层次序列法来求解具有多目标、层次和非线性特征的优化模型。分层序列法根据优化目标的重要性按顺序解决问题,确保满足配置方案的要求。IMA 采用自适应交叉和突变概率,提高了算法的收敛性和质量。最后,案例分析表明,当同时配置蓄热罐和电锅炉时,热电联产系统能获得最佳效益。此外,与 MA、IPSO 和 IABC 算法相比,IMA 算法的平均经济成本分别降低了约 5.11%、2.70% 和 8.43%。

Optimal Configuration of Additional Heat Source for CHP System considering Demand Response Based on Comprehensive Benefits

Optimal Configuration of Additional Heat Source for CHP System considering Demand Response Based on Comprehensive Benefits

An optimal configuration method for the combined heat and power (CHP) system considering demand response is proposed to scientifically and reasonably configure the parameters of the additional heat source and reduce unnecessary investment and construction costs. First, additional heat sources and demand response are utilized to decouple power generation and heating supply, enhancing the flexibility of the CHP system. Second, a multiobjective optimization configuration model of the CHP system is established, taking the system’s comprehensive satisfaction, economic cost, and wind power consumption capacity as the objectives, the unit output, and the capacity parameters of the additional heat source as the decision variables. Furthermore, an improved memetic algorithm (IMA) combined with a hierarchical sequence method is designed to solve the optimization model characterized by multiple objectives, hierarchical levels, and nonlinearity. The hierarchical sequence method solves problems sequentially based on the importance of optimization goals, ensuring the satisfaction of the configuration scheme. The IMA employs adaptive crossover and mutation probabilities, enhancing the algorithm’s convergence and quality. Finally, case analysis demonstrates that the CHP system achieves the best benefits when heat storage tanks and electric boilers are configured simultaneously. Moreover, compared to the MA, IPSO, and IABC algorithms, the IMA algorithm reduces the average economic cost by approximately 5.11%, 2.70%, and 8.43%, respectively.
