计及需求侧响应的电-气耦合配网协同规划
摘要：随着燃气轮机和电转气技术的发展，电-气配网耦合日益加深。另一方面，需求侧响应能削峰填谷，提升系统性能。因此，针对计及需求侧响应的电-气配网协同规划展开研究。首先，在对需求侧响应进行数学分析与建模基础上，以投资成本、维护成本、交易成本和补偿成本之和最小为优化目标，建立配电线路、配气管道、耦合设备规划的混合整数非线性模型。然后，通过分段增量线性化和辅助变量法，将模型化为混合整数线性问题并利用CPLEX求解。最后，将所提方法应用于12节点配电网与10节点配气网的两阶段协同规划，结果表明需求侧响应可降低设备容量需求，减少购能费用，提升规划方案的经济性。
Abstract:With the development of gas turbines and power-to-gas technologies, the coupling of power and gas distribution network is gradually deepened, while demand side response can improve system economy and security by peak-load shifting. Based on the background, this paper proposed a coordinated planning method for power-gas integrated distribution network considering demand side response. Firstly, on the basis of analysis and modeling of demand side response, the mixed integer nonlinear planning optimization model considering distribution lines, pipelines and equipment was established to minimize the sum of investment, maintenance, transaction and compensation cost. Then, the piecewise incremental linearization and auxiliary variable method were adopted to transform it into a mixed integer linear optimization problem, which could be solved by CPLEX. Finally, the results of a 12-bus with 10-node power-gas distribution network planning indicate that, the demand side response can improve system economy by reducing equipment capacity requirements and energy costs.
