The objective of this paper is to review the fast-acting frequency control ancillary services that are currently being implemented or in the development phase in the European power systems. Not only the technical definition of the services will be here explained but also the way in which the services are remunerated. The performance of a flywheel/battery hybrid energy storage plant that has been used as demonstration project to test the capability of both storage technologies to provide fast acting frequency response are summarized in the paper.

Demand response (DR) is needed to maintain the power balance when the proportion of controllable generation decreases. This paper analyses the opportunities to ulitise DR resources in Finland and Portugal. Both countries would benefit from more active demand side participation in system balancing as the amount of inflexible generation is increasing. However, Finland is already shifting from piloting to commercial operation whereas in Portugal, demonstration projects associated with DR aim at paving the way and fomenting discussions around its deregulation in the country.

The electrification of fossil fueled processes and applications is frequently quoted as an essential component for the deep decarbonization of the German energy system. A prerequisite for decarbonization through electrification is low-emission electricity. In the German case, this leads to the so-called “electrification dilemma”, as both a reduction of the emission-intensive conventional power plant park and the significant increase in electricity consumption are driving the demand for RES and guaranteed capacities drastically. In a simulation-based scenario analysis, two measures to reduce emissions in power generation in a high electrification regime are compared: CO2-allowance pricing and a lignite phase-out. Using the DC power flow formulation, the effects on the German transmission grid are determined. The results show that both the coal phase-out and an increase in the CO2-prices lead to a significant reduction in the average CO2-coefficient of power generation. Simultaneously the capacity gap increases significantly, but only for a few hours per year.

Traditionally, electricity markets have been designed with the intention of disabling producer side market power or prohibiting exercising it. Nonetheless it can be assumed that players participating in pool markets and aiming to maximize their individual benefits might depart from the optimum in terms of total system welfare. To recognize and analyze such behavior, system operators have a wide range of methods available. In the here presented paper, one of those methods - deriving a supply function equilibrium - is used and nested in a traditional discontinuous Nash game. The result is a case study that shows that marginal cost bidding thermal producers have an incentive to collaborate on scheduling in order to cause similar effects to tacit collusion.

This paper develops an integrated fundamental investment model which considers both the gas and electricity sector. Furthermore, we adopt the theory of stochastic programming with recourse in the combined model to account for uncertainty in the gas market. This approach enables us to analyze how uncertain gas demand in other sectors affects decisions to invest in electricity generation capacities. We find an overall decrease and a reallocation of investments in gas-fired power plants. We also quantify the expected costs of ignoring uncertainty.

Demand response (DR) is widely seen as a valuable tool to introduce more flexibility into power markets. For the implementation of DR programs, industrial customers seem to offer the greatest potential, given that they are often large single electricity consumers with a certain degree of flexibility. One industrial sector that has received little attention from the literature so far, but shows a large potential for DR, is the wastewater treatment sector. This study examines industrial DR in general and then presents the opportunities for DR from wastewater treatment plants (WWTP) in particular. Three main sources of flexibility can be identified: a potential for variable electricity use in aeration, the time-shifting operation of pumps and the exploitation of overcapacity in the system. In order to quantify system and market effects, DR from WWTPs should be examined by means of an integrated energy systems model.

The increasing integration of wind power in the Portuguese energy market has been raising some challenges in terms of operation and planning of the generation portfolio and of power system management, with ancillary services playing a major role in system stability. A generation company (GENCO) aiming at maximizing its profits has to deal with bids to several available markets, among which are the Day-ahead Market (DAM) and the Secondary Reserve Market (SRM). This paper presents a scheduling solution of a price-maker GENCO whose portfolio comprises a pumped-storage hydro (PSH) unit with variable pumping capacity, acting simultaneously in the DAM and SRM. The results were obtained for four different scenarios, where the PSH may or may not possess variable pumping capacity and compares the PSH behavior in one or both markets simultaneously. The model was implemented in General Algebraic Modeling System (GAMS) as a Mixed Integer Programming (MIP) using CPLEX solver.

This paper investigates the value of bulk energy storage and long-distance interconnectors as enablers towards achieving very high penetration levels of variable renewables. This question is addressed by formulating an optimal grid infrastructure expansion planning problem. It receives input scenarios (such as evolution of generation mix and demand, wind, solar hourly profiles) and computes the optimal investments in cross-region transmission capacity, energy storage and additional generation as well as hourly operational variables, over a 40-year horizon. Illustrative results are presented for selected future scenarios of the European electricity system.

A transition from a traditional power system towards a low-carbon power system requires unlocking new sources of flexibility a t t he distribution level a nd engaging distribution system users to become electricity market participants. These users are usually too small to adequately position themselves in electricity markets. Therefore, the latest package of the European Commission highly encourages aggregating them into a single market entity. Aggregation of distribution system users can be realized through different business models. The main intention of this paper is to analyze two potential business models to be used for aggregation of distribution system users. The first one illustrates the case in which the supplier also offers aggregation services in markets or auctions on behalf of its customers. The second model considers the case in which a new market participant, called the “independent aggregator”, enables distribution system users to actively participate in electricity markets or offer services to the grid operator. The paper elaborates on the advantages of both models through simplified examples by positioning them within the current European market setup.

In terms of the economic performance of residential PV systems, the rate of onsite-consumed electricity (i.e. self-con-sumption) is becoming ever more important. In order to increase self-consumption, battery systems are available, which allow to match electricity generation and consumption. However, relatively small batteries are sufficient to improve self-consumption, and further increases in capacity only lead to small additional self-consumed amounts. Nevertheless, the evolving market offers different additional options to increase profitability and usage of a battery system by offering flat rates or providing balancing power. The business case that provides balancing power achieves an interest rates of 2.1 % (compared to 8% without a battery). Under favourable future conditions, such as increasing household consumption, electricity or balancing power prices, a PV + battery system can be a competitive investment for consumers and the systems' effect on household load profiles has to be considered in the management of balancing groups.
