Impact of Large-Scale Trading of Industrial Flexibility Options on the Operation of a Distribution Grid

Demand side management of flexible factories can reduce energy costs and help to provide incentives to balance supply and demand in the electical energy markets. In a purely profit-optimized trading of the flexibility options, the distribution grid operator has no influence on the load demand of factories, but is affected by the effects. Research paper on the optimization of trading industrial flexibility options have been published by [1]. This paper is based on [1] and analyses the technical effects on the distribution grid. For this purpose, grid analyses are carried out using a case study with an existing distribution grid to determine qualitative effects of marked-driven trades of industrial flexibility. The results are evaluated for violations of permissible grid operating parameters. Results show that existing high equipment loading in the grid area under investigation are slightly intensified by the trade of flexibility options at a high level of penetration. The simultaneous decentralized feed-in of photovoltaic systems can further increase these loadings.
