Evaluation of the impact of RES integration on the Greek electricity market by mid-term simulation

This paper presents a yearly simulation model for the analysis of the impact of the large RES penetration in the energy production mix of Greece on the operation of the Greek electricity market. This impact is analyzed in terms of the electricity market clearing prices, the total CO₂ emissions, the total payment of the consumers for the energy withdrawal and the RES uplift charge, imposed by the government for the payment of the feed-in tariff to the RES producers. A mid-term scheduling model based on the day-ahead market clearing algorithm of the Greek wholesale electricity market is used for the yearly simulation under ten different scenarios regarding the RES installed capacity (multiple RES technologies are considered). Valuable conclusions are drawn from the application of the proposed model for the year 2011.
