摘要:

针对传统风电并网能源调度评价系统设计评估准确率低、系统响应时间慢的不足，提出基于综合模糊理论的能源调度评价系统设计。给出了模糊评价系统的硬件架构与软件实现流程，依托于数据输入管理模块、编辑查询模块、模糊评价模块与数据输入模块构建了可变模糊评价模型，并分别确定出两级的指标评价体系、权重指标和模糊隶属度矩阵；基于模糊算子和模型参数确定出综合评价向量矩阵，实现对并网能源调度方案的精确评价。算例分析结果表明，提出评价系统的平均偏差率可以控制到0.131%，显著优于传统能源调度评价系统。

Abstract:

Aiming at the shortcomings of low accuracy and slow response time of traditional wind power Grid-connected energy dispatching evaluation system, a design of energy dispatching evaluation system based on comprehensive fuzzy theory is proposed. The hardware architecture and software implementation flow of the fuzzy evaluation system are given. Based on data input management module, edit and query module, fuzzy evaluation module and data input module, a variable fuzzy evaluation model is constructed, and two-level index evaluation system, weight index and fuzzy membership matrix are determined respectively. The fuzzy operator and model parameters determine the comprehensive evaluation vector matrix to realize the accurate evaluation of the energy dispatching scheme. The result of the example analysis shows that the average deviation rate of the proposed evaluation system can reach 0.131%, which is significantly better than the traditional evaluation system design.
