区域综合能源系统的源荷类型众多,不同能源之间、负荷之间以及源荷之间呈现相关特性,为此提出一种计及源荷相关性的区域综合能源系统规划方法。首先,采用Nataf变换与Cholesky分解对拉丁超立方采样进行改进,得到了考虑风电、光伏及电、气、冷、热负荷相关性的样本矩阵,进而通过改进聚类中心获得区域综合能源系统的典型源荷场景;然后,建立考虑多元异质源荷相关性的区域综合能源系统规划模型,该模型以投资、运行、外部能源交易成本及弃风弃光成本之和最小为目标函数;最后,基于IEEE 39节点电网系统、比利时20节点气网系统、14节点冷/热网系统组合的区域综合能源系统测试算例进行仿真,验证区域综合能源系统规划中考虑多元异质源荷相关性的必要性及所提方法的可行性。

There are many types of sources and loads in a regional integrated energy system, and there are correlation characteristics between different energy sources, between loads, and between energy sources and loads. Therefore, a planning method for regional integrated energy systems considering the correlation of sources and loads is proposed. Firstly, Nataf transform and Cholesky decomposition are used to improve Latin hypercube sampling, and sample matrices are obtained considering the correlation of wind power, photovoltaic and power, electricity, gas, cooling and heat loads. Then, the typical source and load scenarios of the regional integrated energy system are obtained by improving cluster centers. Secondly, a planning model of regional integrated energy systems considering the correlation of multiple heterogeneous sources and loads is established. The objective function of the model is to minimize the sum of investment, operation, external energy transaction cost and curtailment cost of wind power and photovoltaic power. Finally, a test example based on the combination of the IEEE 39-bus power grid system, Belgium 20-bus gas grid system, and 14-bus cooling/heat grid system is simulated to verify the necessity of considering the correlation of multiple heterogeneous sources and loads in the planning of the regional integrated energy system and the feasibility of the proposed method.
