European authorities are responsible to find the optimal way to integrate them efficiently into the power system to follow the decarbonization process. Market rules penalize traders who close their position in the market without being able to respect it in real market operation. At this regard, the possibility of being able to exchange energy closer to the real time operation helps players to solve forecasts problems. To this aim, a new design of intraday market has been carried at European level focused on the possibility to trade energy continuously until one hour before the delivery. The Italian energy market, historically based on seven auctions, taking part to the Single Intra Day Coupling (SIDC) Market, implemented a hybrid system composed by three auctions and continuous trading. Consequently, the whole system had to face significant changes that impacts on volumes, prices of energy exchanged and agent’s behavior. This paper aims at investigating how the efficiency of the market changes in terms of liquidity and price volatility and the new strategies adopted by players throughout statistical analyses that compare the past structure of intraday Italian market and the current one.","PeriodicalId":495173,"journal":{"name":"International Journal of Smart Grid and Clean Energy","volume":"68 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"136207595","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The proposed approach establishes an optimization model to minimize the Loss Probability of Power Supply (LPSP) and improve the cost-benefit ratio of electricity generation with NCRE, considering different constraints, such as demand, technology costs, available environmental resources, energy storage, and technical limitations. A genetic algorithm that minimizes an objective function dependent on the LPSP and the Levelized Cost of Energy (LCOE) is developed, considering the energy models of a hybrid system composed of solar panels, horizontal axis wind turbines, and an energy storage system. The meteorological conditions for the study area, such as radiation, wind speed, and temperature, are considered, as well as the technical specifications of different models of the systems, to arrive at a solution that allows selecting the best alternatives for a user who wants to implement renewable energy in his household.","PeriodicalId":495173,"journal":{"name":"International Journal of Smart Grid and Clean Energy","volume":"18 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"136207991","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Although environmental sustainability is a hot topic, Day-ahead (DA) scheduling is approached by prioritising the economic perspective, risking sub-optimal CO 2 emission. To highlight the current model limitation, this paper proposes an approach for minimising CO 2 during operation inspired by the Carbon Emission Flow (CEF) method, not revealed by cost optimisation. Although this approach assumes complete energy system control and is less likely to be used for real-world energy dispatching, such a tool creates awareness among stakeholders about the minimum CO 2 limit and the consequences of using specific components or external sources. For this purpose, CEF cost and emission results are compared with cost minimisation with/without CO 2 taxation, confirming that current optimisations objectives cannot achieve the lowest CO 2 emission level. The performances are compared with indices assessing sustainability with insights on dispatching strategies and system components that affect emissions and costs. Finally, to detect if the taxation strategy is suitable for reaching the lowest CO 2 in DA scheduling, a sensitivity analysis was carried out by increasing taxation prices up to 5-times, concluding it would increase costs without reaching the minimum set by the proposed approach.","PeriodicalId":495173,"journal":{"name":"International Journal of Smart Grid and Clean Energy","volume":"87 11 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"136207153","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
