“…Furthermore, the same periods apply to the SMP values. The Greek wholesale electricity market is structured as a mandatory pool market [28]. The energy and ancillary services are simultaneously traded in a day-ahead market and are dispatched on the available generation units.…”

Abstract:The photovoltaic market has recently experienced an enormous expansion, mainly due to the generous Feed-in-Tariffs (FiTs) adopted by many countries. However, in the recent years FiTs have been considerably reduced or even disappeared as their role in the PV deployment has ended. One of the alternatives is the Net-Metering (NEM) policy, which has attracted the interest of stakeholders as it provides a basis for the efficient collaboration between generation and the consumption profiles of the consumer. Currently, there is a lack of a universal policy harmonizing the respective legislations of the E.U. member countries. This paper proposes a novel generalized methodology for the techno-economic assessment of different NEM policies in terms of profitability for the prosumer. The methodology is tested in a formulated case study based on the current NEM policy in Greece. The method proposed uses as inputs the averaged load profiles constructed from real measurements collected from 31 consumers in the Thessaloniki area and evaluated PV production. The current NEM policy and four alternatives are examined, using as additional input the average system marginal prices of the year 2013. The results show that the proposed methodology is capable of evaluating a wide variety of NEM policies and can lead to suggestions for policy adaptation in order to establish a win-win contract between all interested stakeholders.

In this paper, we explore the impact of wind generation on isolated power systems, using the system of Cyprus (an island) as a case study. Since 2010, Cyprus has been facing the challenge of integrating intermittent wind generation, while maintaining a secure and economical power system operation. This integration has raised the reserves requirements, and has undermined the ability to accurately track the unit commitment and dispatch day-ahead plan in real time. To evaluate the impact of these effects, we model the daily electrical power system operation of Cyprus as a day-ahead unit commitment and economic dispatch problem, and simulate the system for a long horizon of many days, under different scenarios of wind penetration, using historical data of wind generation.

IndexTerms--Wholesale electricity market, unit commitment, bid/cost recovery, sensitivity analysis. Abstract--TheGreek wholesale electricity market is based on a day-ahead unit commitment market clearing and generation dispatch formulation with co-optimization of energy and reserves without the participation of transmission. An important feature of the market design is the cost recovery mechanism, which explicitly compensates generation units for their commitment costs and guarantees a minimum profit equal to 10% of their variable costs. In this paper, we evaluate the current mechanism in comparison to an alternative bid/cost recovery mechanism by simulating the wholesale electricity market for a period of one year. As part of the study we take into account the forthcoming changes for the liberalization of the Greek market that include the physical and virtual sale of a portion of PPC lignite plants, and we examine a likely "business as usual" scenario concerning the resulting bidding strategies. Lastly, we perform a sensitivity analysis with respect to the hydro production and the carbon price.
