The concept of evolution in technology and biology is discussed. It appears that most of the evolution trends in technology and biology result from different development strategies. This conflict has roots from the time when technology emerged to adapt the environment for our needs. Following that strategy to full extent is dangerous. We need also to adapt to the environment, but current techno...

We conduct an empirical analysis of electricity forward prices using a high-frequency data set of hourly spot and day-ahead forward prices. We find that there are significant risk premia in electricity forward prices. These premia vary systematically throughout the day and are directly related to economic risk factors such as the volatility of unexpected changes in prices and demand as well as ...

Day-ahead energy market clearing relies on a deterministic equivalent model with a limited time horizon, which may lead to inefficient scheduling of generating units from the point of view of generators. For this reason, generators may wish to forgo the profit hedging offered by day-ahead electricity markets and assume the risk of self-committing their units with the hope of securing greater pr...

In this paper, a two-stage optimal charging scheme based on transactive control is proposed for the aggregator to manage day-ahead electricity procurement and real-time EV charging management in order to minimize its total operating cost. The day-ahead electricity procurement considers both the day-ahead energy cost and expected real-time operation cost. In the real-time charging management, th...

This paper presents an analysis of how day-ahead electricity spot prices are affected by day-ahead wind power forecasts. Demonstration of this relationship is given as a test case for the Western Danish price area of the Nord Pool’s Elspot market. Impact on the average price behaviour is investigated as well as that on the distributional properties of the price. By using a non-parametric regres...

This paper introduces a weather-based method for short-term forecasting of aggregate electricity load. We extract the weatherand illumination-dependent load via least-squares fitting for load versus Steadman apparent temperature and logscale natural illumination. A separate fit is done for each hour of the day, and then Fourier-transform-based spectral analysis handles the resulting residual. T...

Understanding power prices dynamics is crucial for valuing flexibility assets such as storage or flexible consumption facilities that accommodate fluctuations in supply from variable renewables. Owners of need to know how extreme can become order optimally manage (dis)charging adjusting volumes. We examine predict those high and low prices, being the different quantiles price probability distri...
