主讲内容:

    Regions with abundant wind resources usually have no ready access to the existing electric grid. However, building transmission lines that instantaneously deliver all geographically distributed wind energy can be costly. Energy storage (ES) systems can help reduce the cost of bridging wind farms and grid, and mitigate the intermittency of wind outputs. In this paper, we propose models of transmission network planning with co-location of ES systems. Our models determine the sizes and sites of ES systems as well as the associated topology and capacity of the transmission network under the feed-in-tariff (FIT) policy instrument. We first formulate a location model as a mixed integer second-order-conic program (MISOCP) to solve for the ES-transmission network design with uncapacitated storage. Then we propose a method to choose ES sizes by deriving a closed-form upper bound. The major insight is that, in most cases, using even small-sized ES systems can significantly reduce the total expected cost, but their marginal values diminish faster than those of the transmission lines as their capacities expand. Despite uncertainties in climate, technologies and construction costs, the cost-ecient infrastructure layout is remarkably robust. We also identify the major bottleneck cost factors for different forms of ES technologies.
