Development of a Design and Value Evaluation Tool for the Optimal Connection between Renewable Energy Generation and Energy Storage System

Many countries have increased Renewable Energy Generation (REG) to reduce greenhouse gas emissions. The more we install REG, the more we damage the reliability of electric distribution system and the stability of grid. We need to analyze the effect of REG on grid for the optimal connection between REG and Energy Storage System (ESS), need to research the reliability index and the flexibility index of the optimal connection between REG and ESS to maximize the reliability of electric distribution system and the stability of grid, and need to develop a design and value evaluation tool that can contribute to the stability of grid. In this paper, we describe the operational process of a design and value evaluation tool for the optimal connection between REG and ESS, and explain our design and value evaluation tool for the optimal connection between REG and ESS. And we show the element technology of a design and value evaluation tool with measured past yearly PV data. Finally we explain the element technology of a design and value evaluation tool without measured past yearly PV data.
