An approach for an optimization problem to combine acquisition of a balancing group and grid restrictions given by distribution system operators is introduced in this paper. It is embedded into an extended scheduling system which enables communication between balance responsible parties and system operators. As the optimization problem should be used inside a DayAhead or IntraDay process it was formulated...
Due to increasing contribution of renewable energy sources to the overall energy production, future control of energy consumption should achieve the principle ‘generation following demand’. Within this approach, also known as demand side management, consumers are prompted to alter demands through an incentive signal. This work addresses the use of variable price as such incentive signal to influence...
An approach for an extended market grid operation is introduced in this paper. Therefore a Market System Operator as a new role in the electricity economy is defined and an extended ENTSO-e scheduling system is developed. Additionally a traffic light system for distribution grids is integrated. The special part of renewable energy sources with their specific character is taken into account. The aim...
By influencing the demand side by means of price signals (Demand Response) additional flexibility potential in electric supply systems can be provided. However, by influencing the demand side typical consumption patterns of previously unaffected consumers are changed. This will lead to increasing uncertainty in load forecasting. This paper deals with the forecast of load time series in consideration...
The article analyses effects of price signals on the consumption behavior of household electricity customers. It proposes a systematic analysis process consisting of data preprocessing, aggregation steps and clustering methods. This analysis process was applied to two smart meter datasets (Olympic Peninsula Project, RESIDENS). Large fluctuations in customers' response to the same price signal were...
In this paper, a fundamental optimization model containing the German generation and energy storage system has been used to analyze the profitability of pumped-storage power plants within the German energy market. As a result of the optimization, energy prices are calculated based on the power plants' marginal costs according to the merit order principle. This paper demonstrates the influence of increasing...
