| 鉴于热网潮流方程存在强非线性与强耦合特性，提出了一种基于多元函数泰勒展开的线性优化方法，该方法将复杂的非线性优化问题转化为多个易于求解的线性优化问题，各线性优化问题之间采用迭代方法逐步逼近最优解。以 电-热互联系统总网络损耗最小为优化目标，可同时实现对多个热电联产机组的参数优化配置，降低了网络损耗，减少了系统运行成本，有利于实现不同能源之间的耦合互补与协调运行，从而提升系统调度能力、经济性和安全性。实际系统的测试分析验证了所提方法的有效性与合理性。 |

| In view of the strong nonlinear and strong coupling characteristics of the heat flow equation, a linear optimization method based on multivariate function taylor expansion is proposed. This method transforms the complex nonlinear optimization problem into multiple linear optimization problems that are easy to solve. An iterative method is used to gradually approximate the optimal solution between optimization problems. Taking the minimum total network loss of the electro thermal interconnect system as the optimization goal, the parameter optimization configuration of multiple cogeneration units can be realized at the same time, the network loss is reduced, the system operation cost is reduced, and coupling complementarity and coordinated operation is achieved between different energy sources, which can improve system scheduling, economy and security. The test analysis of the actual system verifies the validity and rationality of the proposed method. |
