摘要:

将互联微电网与配电系统运行(DSO)合作可以提高运行和可靠性。研究了可再生能源高度渗透的互联微电网的优化运行和调度问题。此外,一个有效的随机框架的基础上的无迹变换(UT)的方法,提出了模型的不确定性与小时的市场价格,小时的负荷需求和DER的输出功率。在能量管理之前,采用新开发的线性化技术对从交流潮流中提取的节点方程进行线性化。所提出的随机问题被制定为一个单目标最优化问题最小化互联AC MG费用函数。为了验证所提出的技术,修改后的IEEE 69节点网络作为测试用例进行了研究。

英文摘要:

Cooperating interconnected microgrids with the Distribution System Operation (DSO) can lead to an improvement in terms of operation and reliability. This paper investigates the optimal operation and scheduling of interconnected microgrids highly penetrated by renewable energy resources (DERs). Moreover, an efficient stochastic framework based on the Unscented Transform (UT) method is proposed to model uncertainties associated with the hourly market price, hourly load demand and DERs output power. Prior to the energy management, a newly developed linearization technique is employed to linearize nodal equations extracted from the AC power flow. The proposed stochastic problem is formulated as a single-objective optimization problem minimizing the interconnected AC MGs cost function. In order to validate the proposed technique, a modified IEEE 69 bus network is studied as the test case.
