Their risk depends on technical and financial elements. When some corporations decide to invest in a plant, they decide to take all above-mentioned risks. The question “Given a specific investor, a specific plant, etc., how big are the investment risks?” has not a clear answer. In fact, the impact of the previous risk factors on cash flows is not completely quantified, mainly because all the risks are related, but the dependency structure is difficult to be modelled. Hence, it is important to have a measure of the impact of the risks into the cash flows. Due to the lack of knowledge in this quantification, we have decided to investigate it more in the detail. The paper aims to measure the variability of cash flows and how effective are the strategies for locking electricity prices, ship freight rates, or both in the reduction of this variability. We adopt the Monte Carlo approach for simulating all the possible cash flows and for measuring all the uncertainties. The output shows that seasonal and uncertain cash flows. The strategies, for reducing the probability of negative cash flows, work only with locked electricity prices.","PeriodicalId":388023,"journal":{"name":"2017 6th International Conference on Clean Electrical Power (ICCEP)","volume":"29 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-08-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128237457","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}

This is realized through the employment of cluster analysis, which classifies offshore wind energy investors - who have purchased equity stakes-in terms of the entry timing, exit timing, purchase timing and stake purchased. We, then, perform a SWOT analysis to identify the major strengths, weaknesses, opportunities and threats encountered by each cluster of stakeholders. Cluster analysis revealed the existence of three distinct investment strategy profiles: i) Late entry investors, ii) Pre-commissioning investors, and iii) Own-build-transfer investors. Corporate and institutional investors tend to be late entry investors, whose strategy is based on buying assets while they are fully operational avoiding construction risks, retaining a risk aversion profile. The exit timing of OEMs and EPCI contractors usually takes place before or right after the commissioning of the wind farm. Finally, major Utilities tend to keep the operating assets on their balance sheet and divest only part of them (mostly minority stakes) during the operating stage; Independent energy companies are found in both 2nd and 3rd cluster; however, exceptions may be observed.","PeriodicalId":388023,"journal":{"name":"2017 6th International Conference on Clean Electrical Power (ICCEP)","volume":"282 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-08-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123238480","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}

Particularly, uncertain output depending on weather condition gives a large impact on frequency regulation. In this paper, we proposed a frequency control method in power systems based on balancing market with applying a penalty to forecasting error of the wind power output. Based on the situation in supply and demand balance in the power system, it is assumed that the owners of the wind power plants may find the optimal output which maximizes the owners' benefit with considering output curtailment and penalties corresponding to the forecasting error. It is the goal to maintain system frequency more efficiently, which means the better supply and demand balance. We performed a simulation based on power system model including generator dynamics, network and balancing market in order to confirm the variation in frequency. In addition, we calculated the price signal to be given to players in the balancing market and penalties with respect to players including generators, customers and the owners of wind power plants in the balancing market.","PeriodicalId":388023,"journal":{"name":"2017 6th International Conference on Clean Electrical Power (ICCEP)","volume":"32 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-08-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134424836","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}

These curves are function of instantaneous solar irradiation and cell temperature; and outline the maximum power that the system can supply at any given moment. As a consequence of this PV systems lack overload capacity, which is common in traditional rotating generators; and therefore, PV systems cannot supply short term or transient load demands. To solve this issue two approaches can be taken; one is to constantly operate the PV system below its maximum power level, which has the drawback of non-optimal energy harvesting. The other is integration of energy storage elements to the power conditioning system, which allows optimizing power generation, while adding overload capacity. In addition, this approach also allows smoothing out short term irradiation variations allowing the system to improve energy harvesting. Focusing on the second approach analysis of short term energy storage requirements in PV systems is performed in this paper. As a result, sizing guidelines and a design procedure for a supercapacitor based energy storage system are developed. In addition, effectiveness of the proposed method on improving PV generator performance is tested and verified through computer simulations.","PeriodicalId":388023,"journal":{"name":"2017 6th International Conference on Clean Electrical Power (ICCEP)","volume":"131 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-06-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127035896","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}
