摘要

重组和放松管制使输电计划者面临新的目标和不确定性。因此,在放松管制的电力市场中,输电扩展规划(TEP)需要新的标准和方法。本文提出了一种新的TEP市场化方法。提出了一种改进的差分进化模型来解决这一新的市场TEP问题。与简单差分进化方法相比,EDE方法的改进之处有:1)缩放因子F在一定范围内随机变化,2)使用辅助集来增强种群的多样性,3)将新生成的试验向量与最近的亲本进行比较,4)使用简单可行性规则来处理约束。在ieee30总线测试系统上的应用结果证明了该方法解决TEP问题的可行性和实用性。

Transmission expansion planning by enhanced differential evolution
The restructuring and deregulation has exposed the transmission planner to new objectives and uncertainties. As a result, new criteria and approaches are needed for transmission expansion planning (TEP) in deregulated electricity markets. This paper proposes a new market-based approach for TEP. An enhanced differential evolution (EDE) model is proposed for the solution of this new market-based TEP problem. The modifications of EDE in comparison to the simple differential evolution method are: 1) the scaling factor F is varied randomly within some range, 2) an auxiliary set is employed to enhance the diversity of the population, 3) the newly generated trial vector is compared with the nearest parent, and 4) the simple feasibility rule is used to treat the constraints. Results from the application of the proposed method on the IEEE 30 bus test system demonstrate the feasibility and practicality of the proposed EDE for the solution of TEP problem.
