摘　　要：分析了智能电网机制下电网—用户互操作性(GCI)的实现基础及对负荷曲线的影响。GCI具有模糊性与自适应性,传统建模方法很难定量模拟,智能工程混合模型为其提供了解决思路。根据GCI的特点建立了智能工程混合模型,包括控制中心智能体、发电智能体、用户智能体等。在电力市场环境下,用户智能体根据实时电价的波动及可响应负荷的大小进行模糊推理,改变电力消费行为,从而影响负荷曲线。通过IEEE 39节点新英格兰系统算例,验证了该定量模拟方法及智能工程混合模型建模技术的有效性。Grid-consumer interoperability （GCI） implementation foundation and its effects on load curve in a smart grid are analyzed. Basically GCI is fuzzy and adaptive, as a result, it is difficult to quantitatively simulate GCI effect by traditional modeling technology. Intelligent engineering hybrid model is a promising modeling tool to address such difficulty. Based on the characteristics of GCI, an intelligent engineering hybrid model is developed. The model includes control center agent, generation agent and consumer agent. Consumer agent fuzzily inferences its electricity consumption behavior based on the fluctuation of real time price and the size of responsive load in the electricity market environment, then load curve is influenced further. Simulation on IEEE 39-bus New England system demonstrates the validity of proposed quantitative simulation approach and the intelligent engineering hybrid modeling technique.
