The integration of the day-ahead electricity markets in Europe shall lead to one multi-area market that will substitute the local/national ones. In view of the “target model” that will be enforced in all European markets in conjunction with their forthcoming coupling/integration, a centralized market splitting algorithm is implemented in this(More)
This paper presents the solution algorithm and test results of the market-splitting approach, proposed in the first part of this two-paper series, for the clearing of the forthcoming Internal Electricity Market. The market-splitting approach is implemented in a Europe-wide level, indicatively defining three power pools and 22 power exchanges, comprising 42(More)
A centralized market-splitting algorithm is implemented in this paper in a Europe-wide level, comprising both power pools and Power Exchanges, with each local/national market respecting the standard constraints imposed by its own regulatory framework, including the full set of unit technical/commitment constraints and system operating constraints in power(More)
The determination of reserves in a power system with high wind penetration is necessary to maintain the system balance in an economic way, especially in insular power systems where no interconnections to neighboring systems exist. This paper addresses the problem of quantifying the amount of spinning and non-spinning load-following reserves required for the(More)
In view of the forthcoming large-scale RES penetration, physical markets should check the feasibility of the electricity market clearing against their internal (intra-zonal) transmission network constraints, considering full network topology. Three methods for the solution of a market-splitting problem in a Europe-wide level are implemented in this paper.(More)
The increasing shares of renewable energy in power systems have a significant impact on the operation of electricity markets and grids worldwide. This paper provides an overview of the main challenges that high shares of renewable generation introduce in the power system management and electricity markets operation as well as a brief description of(More)
The integration of the European electricity market constitutes a critical and contemporary issue, expected to take place within year 2015. In view of the forthcoming RES penetration, physical markets with unit-based offers-either power pools or Power Exchanges (PXs)-check the feasibility of the electricity market solution against their intra-zonal(More)
Recent developments in European Union's legal and regulatory frameworks are leading to the creation of the Internal Electricity Market, which will substitute the local spot electricity markets. In this direction, a volume-based market coupling approach between a Power Exchange (PX) and a power pool is implemented in this paper, in order to examine the(More)
This paper presents a deterministic unified unit commitment and economic dispatch model that integrates storage devices in the short-term power system scheduling under high renewable energy penetration. The presented model is a single multi-hour look-ahead real time tool that uses multiple time resolution to reduce its computational requirements. Operating(More)
The “Target Model” for the European electricity markets integration has received the attention of regulators, economists and market designers in the last years, namely the substitution of local electricity markets with a harmonized multi-area market, with same market segments in all European countries. In view of this market integration, a(More)
