Abstract |
This paper studies and proposes an economic analysis of power system reinforcement and flexible interconnection to increase hosting capacity from the grid operator's point of view. Recently, as DER(Distributed Energy Resources) has rapidly increased, the grid operator must perform system reinforcement in order to stably connect DER to the grid. However, in order to reinforce the system, it is essential to analyze the economic analysis because a large initial investment cost is incurred. Therefore, in this paper, considering the cost compensation of power curtailment, an algorithm is proposed that allows the grid operator to perform economic analysis between grid reinforcement and Flexible Interconnection and determine the connection plan when operating the grid for DER interconnection. In particular, this paper analyzed the economic impact of factors affecting economic efficiency through sensitivity analysis. |
