Marketing of Wind Energy in the Intraday-Market

The stochastic nature of electricity generation based on wind has a strong impact on the open volume and traded prices on the intraday market for electricity at the EPEX SPOT power exchange. Transmission system operators (TSOs) have to market this electricity on the day ahead as well as on the intraday market. The ior/cf-HSG developed an automated trading algorithm which incorporates the price and volume stochastics and takes the relevant risk management guidelines into account. The algorithm is embedded into a commercial energy trading system and automatically places orders on the intraday market in order to effectively manage the TSO's net position which varies due to periodically changing generation prognoses and – of course – own intraday market transactions.

The allocation of short run infeed and flexibility can even exhibit positive effects on the overall efficiency and fluctuation.
