Dimensioning and procurement of sufficient balancing reserves are elementary to safeguard operational security as well as frequency quality. Nevertheless, the current development and structural changes in the electrical power system lead to new challenging tasks in terms of balancing the system while using the interconnected system and resources in an efficient way. This as well as the increasing volatile feed-in of renewable energy sources rises the questions of the validity of static methods to dimension reserves. Therefore, this paper presents a method to determine the demand of balancing reserve with a dynamic approach — allowing to take the effects of the Imbalance Netting Process into account. Notwithstanding, a sufficient amount of balancing reserves in every situation has to be determined to ensure a secure network operation at all times.

Bidders in day-ahead electricity markets want to sell/buy electricity when their bids generate positive surplus and not to take an action when the reverse holds. However, non-convexities in these markets cause conflicts between the actions that the bidders want to take and the actual market results. In this work, we investigate the non-convex market clearing problem of Turkish market operator and propose three different rule sets. The first rule set allows both rejection of bids with positive surplus and acceptance of bids with negative surplus. The second and the third sets only allow one of these conflicted cases. By using total surplus maximization as the objective, we formulate three models and statistically explore their performance with the real data taken from Turkish market operator.

The global natural gas market is undergoing substantial changes by 2020. Therefore, studying these changes and their impacts is of high importance. In this study, a mixed complementarity model is used to simulate the global natural gas market for 2020. Further, scenarios on the key changes in the future natural gas system are defined and their impact investigated. In particular, shale gas developments as well as new transmission capacities are investigated. The results of simulation show that, the U.S. as a new LNG supplier can considerably affect the global natural gas market. In this case, a reduction of 20% on LNG wholesale prices with respect to 2015 is observed. This may lead to higher natural gas consumption in LNG dependent countries. In additions, results of simulation indicate that, setting up new transmission infrastructure as well as new pipelines within Europe, will not influence the wholesale prices.

While the majority of electricity in the Nordic and Baltic countries is traded at the day-ahead market, producers and consumers can use the intraday market to adjust their production commitments according to updated forecasts closer to the time of delivery. This reduces the need for balancing, particularly important for VRE producers, but it also means that the price formation at intraday market can change optimal bidding strategy in the day-ahead market. Through econometric modelling of intraday price premiums, this paper investigates intraday price asymmetries, which potentially can lead to strategic bidding. The intraday market is per definition symmetric, as prices for power sales always correspond to prices for power purchases, however, we find that this symmetry is not reflected in the price structure in regards to the total load adjustment needs.

Model-based analysis is assigned a central role in the discussions on how to design the energy system and yet there is substantial need for further research here, especially in mapping power demand and load development with high spatial resolution (NUTS 3). A methodological approach is developed in this study that addresses this research gap using sequential bottom-up modelling analyses. The result shows that the sectoral composition of electricity demand in particular causes regional variations in load patterns. Using the method we developed, conclusions can also be drawn regarding future regional load development. A future increase in peak loads is to be expected, which will be concentrated on regions with high levels of electric mobility. It will not be possible to absorb this increase by smart management of vehicle charging alone.

Auctions is an increasingly popular instrument for introducing competitiveness in the support schemes for renewable energy, however, designing successful auctions appears to be a challenge. Policy makers seeking to introduce auctions are faced with a range of design choices, which may affect the auction outcome significantly. This paper investigates the past experiences with auction implementations in 13 countries. We highlight popular design choices and evaluate auction performances based on a set of assessment criteria. We find that as a market-based support mechanism auctions can help driving down support costs, however, they are also prone to design errors. Adjusting the auction design to the specific conditions (national and marked) is a key parameter for success.

In this paper, we study the development options of tariff structures in electricity distribution in Finland. We compare the impacts of three different tariffs from the viewpoints of customers, distribution system operator (DSO), electricity supplier, and society. Analyzed tariffs are (1) energy oriented tariff, which is currently in use, (2) power limit tariff, and (3) power tariff. Based on the analyses, it seems that it is justified to include power based price component in distribution tariff. Generally, the impacts of both analyzed power based tariffs are quite similar. However, it seems that power tariff is a bit stronger candidate. Nevertheless, it should be noted that the benefits of the power-oriented pricing, illustrated in the paper, could be achieved only by well-designed tariff system. Although analyses are based on Finnish case, most of the results are generalizable to other countries also.

Energy storage and demand response (DR) are options for coping with the rising share of intermittent renewable generation in countries attempting to reduce environmental damage from electricity. So far little is known about the potential and the impact of DR on the system and on the markets. In this research, it is shown how electricity demand can be derived rationally from reasonable preferences for consumption timing in an environment of load- and price uncertainty. This demand is then aggregated to the market level and a timing market equilibrium is defined. It is then discussed if DR can be considered as a “storage” technology.

The paper presents the analysis of coordinated power flows in Central Eastern Europe(CEE) region (Germany, Poland, Czech Republic and Slovakia) interconnected by the AC power lines. Analysis is undertaken in two aspects technical and economic and covers the period from 1st of January 2015 till 30th of November 2016. The paper embraces comparison between planned and real (measured) power flows with justifying flow compatibility with the prices and checking market functioning. The paper relates to the loop flows in this region and analyses the impact of the PST commissioning on the Polish German border on 22nd of July 2016. The article is based on the official market data (planned flows) and atual values of the flow (real flows) on the cross-borders.

The rapid growth of variable renewable energy (VRE) and the expected decrease of conventional generation capacities will generate more flexibility needs in power systems and require flexibility resources to be activated. Flexibility potentials do exist, whether they refer to installed generation, load adjustment or to a greater coupling to other energy sectors. In this paper, we identify the framework conditions that influence the provision of VRE-friendly flexibility in the Nordic and Baltic electricity sector, i.e., the market and regulatory settings that act as drivers or barriers to flexibility. We find that the most restrictive barriers against flexibility are emitted by public authorities as part of broader policy strategies. Overall, we find that current regulatory and market framework conditions do not hinder flexibility. However, despite that, flexibility remains limited due to a lack of coherent instruments intended to both the demand and supply-side to effectively act flexibly.
