Abstract

The commercial and industrial microgrid (CIM) based on renewable energy sources is a solution to the environmental problems. This paper examines CIM based on renewable energy sources connected to the power system by one power transmission line. The power flow from the power system and the limits of its deviations are determined in advance. Compliance with the limits is a basic condition when design of daily load profiles in CIM, because this guarantees uninterrupted power supply from the power system at normal prices. The research is aimed at solving the problem of generating daily load profiles for CIM. The problem is solved using the resources of active consumers registered in the demand management program based on the “load shifting” technique and considering the resources of energy storage systems. An algorithm for generating daily load profiles is developed, which allows the use of various methods for calculating the optimal allocation of shifted load. The proposed algorithm was tested on a 6-node circuit. The resulting daily load profiles satisfy the specified conditions.

设计基于可再生能源的工商业微电网的日负荷曲线

基于可再生能源的工商业微电网（CIM）是环境问题的一种解决方案。本文研究了通过一条输电线路与电力系统相连的基于可再生能源的 CIM。电力系统的功率流及其偏差限制是事先确定的。在 CIM 中设计日负荷曲线时，遵守限值是一个基本条件，因为这可以保证电力系统以正常价格不间断供电。本研究旨在解决为 CIM 生成日负荷曲线的问题。在 "负荷转移 "技术的基础上，利用需求管理计划中登记的活跃用户资源，并考虑到储能系统资源，来解决这个问题。开发了一种生成日负荷曲线的算法，该算法允许使用各种方法计算转移负荷的最优分配。在一个 6 节点电路上对所提出的算法进行了测试。得出的日负荷曲线满足指定条件。
