摘要
针对电热综合能源系统中网络传输损耗对供需平衡的影响,提出一种多目标优化调度策略以最小化系统经济环境调度目标,并且实现电热能源之间的协调与优化。首先,提出一种计及网络传输损耗的电热综合能源系统多目标优化调度模型,该模型同时考虑电传输损耗和热传输损耗;其次,依据公式化的非线性耦合优化问题获得协调方程,以此分析机组出力的协调关系;然后,设计一种双层双l迭代算法以有效求解此多目标优化调度问题,该算法能够减少计算负担以具备更快的收敛速度;最终,通过5个仿真算例验证所提算法的有效性。
To research the effect of network transmission losses on supply-demand balance in integrated electro-heating system(IEHS),a multi-objective optimization dispatch strategy is proposed to minimize gas emission and realize economic dispatch in this paper.Firstly,a multi-objective optimization dispatch model for IEHS considering transmission losses is established,where both power and heat transmission losses are considered with satisfactory accuracy.Then,the coordination equation is obtained from the formulated non-linear coupling optimization problem to analyze the coordination relationship of units’outputs.Besides,a double-layer double-l-iteration algorithm is presented,which can effectively solve this multi-objective optimization dispatch problem and decrease computation burdens with faster convergence rate.Finally,simulations performed on five case studies demonstrate the effectiveness of the proposed method.
