European network operators are responsible for covering and procuring the electricity lost on their grid. The authors introduce a transparent and reproducible method to model a risk averse trader behavior. The main elements of procurement cost and the resulting energy tariff for network operators are identified and estimated. The presented price calculation model is based on publicly available power...
There are novel technical solutions and complex market roles in the energy market that cannot be associated with one single market participant and thus are difficult to be fitted into the current energy market environment. The article analyzes these assets and roles to help regulators encourage the spread of energy storage assets, enable demand-side flexibility and its appearance on the flexibility...
The unification of the day-ahead power exchanges resulted in a varying set of order types, which leads to challenges in the formalization of mathematical models and clearing procedures. In our paper, we have focused on complex orders. Complex orders have been in use in the Iberian power markets for many years, and they have been involved in the EUPHEMIA [1] as well, which is the clearing algorithm...
Direct Load Control in several countries still mean the remote control of electric storage water heaters by Ripple Control (RC) or by Long-Wave Radio Control (LWRC) technology. However this control could be extended to other appliances like freezers, air-conditioners or electric vehicles. Basically, the paper investigates the control following capability of such appliances as well as the impact of...
A new market design is proposed which employs a joint day-ahead trading platform for energy and security reserves; its main purpose is to address the growing European difficulties in the procurement of ancillary services. This paper is the second part of the proposal's synthesis. The outline of the mathematical programming model is followed by the general description of the developed prototype software...
A new market design is proposed which employs a joint day-ahead (DAM) trading platform for energy and security reserves. Its main purpose is to address the growing difficulties in the procurement of European ancillary services. This paper is the first part of the resulting research project's synthesis. The concept of co-optimization is described, followed by a proposal of a co-optimized power exchange...
The topic of this paper is the introduction of a new offer structure type for a co-optimized day-ahead energy market. Co-optimization refers to that energy and reserve are procured simultaneously in the same algorithm. This algorithm can comply with the EUPHEMIA, the algorithm developed for the all-European market coupling. The paper discusses the required supplements and describes the bidding method...
Though European day-ahead power exchanges (PXs) generally operate in an environment where participants are self-scheduling, PXs are still supposed to provide clearing results which are rather close to real technical and economic feasibility. The diverse constraints of power plants are of particular concern in this regard, because their proper handling can be difficult even with advanced mathematical...
In this paper we propose market designs that incorporate the beneficial method of co-optimization to the European energy markets with predominantly sequential energy and control reserve procurement. Co-optimization refers to that reserves are procured and priced jointly with the energy in the same market clearing algorithm. We found that different day-ahead market designs can be formulated, all achieving...
Recent trend in expansion of intermittent power capacity in Europe invokes more demand for power control services and innovation in their market. In this paper, a market arrangement that enables simultaneous power exchange clearing and reserve capacity procurement is proposed. Motivation of implementing such co-optimized short term market in liberalized self-scheduling, power markets is discussed...
Day-ahead electricity markets (DAMs) receive increasing attention in research, operation and among traders. Coupling these markets is the focus area of creating the Euro-pean Internal Electricity Market (IEM). In the near future novel, so called flow-based transmission capacity allocation methods should be applied in this integrated market, as it is enforced by the IEM target model.
The small generation units including cogeneration units and renewables have been widely spread during the last decades. These units raise several questions regarding the power system, e.g., their integration into power system control or their role on the supply-side of smart grids. A multiagent model was established in order to facilitate the investigations of the emerged questions. Several viewpoints...
Distributed generation have been widely spread in the last decades raising a lot of questions regarding the safe and high-quality operation of the power systems. The investigation of these questions requires a proper model considering the different technical, economical and legal aspects. The goal of our research was to develop a multiagent system where rational agents control each distributed generation...
A clearing algorithm was implemented and is under further development to provide a tool for modeling the effect of the planned couplings of the European day-ahead markets. In this paper the effect of the coupling of the Czech, Slovak and Hungarian power exchanges is presented. The paper also analyses the effect of the introduction of block products on the liquidity of the Hungarian Power Exchange,...
