With a growing number of distributed energy resources, the electricity network is challenged with a higher quantity of technical problems such as capacity congestions and over- or under-voltages. One often-discussed approach to solve these problems, especially in the European zonal electricity...

This paper evaluates investment incentives for wind power under uniform and nodal pricing.An electricity system model is developed, which allows for investments into wind power whileconsidering transmission grid constraints in detail. Targeting equally high wind capacitiesunder nodal and uniform...

As redispatch costs and their associated distributional impacts continue to rise, the discussion on reconfiguring bidding zones in European power markets persists. However, determining an appropriate bidding zone configuration is a non-trivial task, as it must prove beneficial under varying...

Due to increasing shares of renewable energies in electricity production, the cost-effective system integration of these installations is becoming more and more important. Technologies and locations are viewed as system-friendly when they are more cost-efficient and easier to integrate because...

The European Directive on common rules for the internal market in electricity (2009/72/EC) requires all member states to 'ensure the implementation of intelligent metering systems' in order to foster a more active involvement of customers in the electricity market. Such intelligent metering...

The market-based procurement of system services for network operators is gaining momentum in the current debate about the future market design in the energy sector. Since current sources of reactive power are primarily fossil-fuel power plants which will not be available in a carbon neutral...

A shift from zonal pricing to smaller zones and nodal pricing improves efficiency and security of system operation. Resulting price changes do however also shift profits and surplus between and across generation and load. As individual actorscan lose, they might oppose any reform. We explore how...

Strongly correlated and spatially concentrated curtailment of power plants strongly affects the electricity market. Such curtailment is observed during heat waves in middle Europe, for example. First, curtailed power plants need to be substituted by more expensive ones. Second, additional...

This paper investigates the incentives market participants have in the German electricity balancing mechanism. Strategic over- and undersupply positions are the result of existing stochastic arbitrage opportunities between the spot market and the balancing mechanism. This strategic behavior can...

This article analyses the flexibility of the German power market with respect to the integration of an increasing share of electricity from renewable energy sources. Flexibility limiting system components, which cause negative prices are explained and illustrated for the German market. Then, the...
