The feasibility of using the automatic generation control with energy capacitor system is implemented to both areas. Wind turbines are considered to be one of the most used alternative sources of energy to solve global warming worldwide. The output of wind turbines depends on the weather condition which causes large fluctuation in the power output when WTs connect to the system. So, the system should be capable of handling uncertainties caused by the wind turbines and load variations. H∞ loop-shaping method is designed as the proposed controller which is used to regulate and improve system stability in the hydro thermal power system. Results demonstrate that the hydro thermal system with CS-based H∞-controller gives higher system stability and more robustness than the hydro thermal system with ECS-based PID controller.","PeriodicalId":360947,"journal":{"name":"International Journal of Process Systems Engineering","volume":"73 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-08-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132160896","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}

Repurposed hybrid electric vehicle lithium ion batteries have been shown to have energy storage potential at a modest capital cost. In this paper, the authors use a two stage MatLAB simulation to create and optimise, a net zero grid-connected facility. The yearly electricity price is calculated under various scenarios using two different pricing structures, fixed feed-in tariff and market pricing. The facility under consideration is a commercial distribution centre with refrigeration, onsite generation of hydrogen for fuel cell powered forklifts, solar and wind power generation, and re-purposed batteries for energy storage. Importantly, the feed-in tariff mechanism is shown to be a deterrent to implementing energy storage onsite, as well as to increasing the use of locally generated power. Although further savings are possible in the model, when energy storage is used, close to $50,000 in savings can be seen from electrolyser load shifting that requires no capital investment. The mechanism also negatively influences indirect electricity emissions, which is not consistent with environmental objectives.","PeriodicalId":360947,"journal":{"name":"International Journal of Process Systems Engineering","volume":"62 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-08-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122837140","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}

After introducing the methodological framework for risk assessment, we take a look at an overview of the three methods. From a perspective shaped by systemic paradigm, we propose the concept of symptom, as thread running through of each method. After detailing the specific symptoms for each method, we put forward two hypotheses. First, a method is not neutral and symptoms are a sign of inclination and drive representations of the scenarios developed. Second, risk assessment workshops, seen as privileged locations for organisational learning, change the relationship between actors and hazardous situations. By locating each method within the triangulation of definition from the systemic paradigm, we invite risk assessment experts to make their tacit knowledge as explicit as possible in order to identify operational levers to control their activity.","PeriodicalId":360947,"journal":{"name":"International Journal of Process Systems Engineering","volume":"36 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-06-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134187329","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}

Key to providing quality decision options is an appropriate method of combining, or fusing, these heterogeneous evidence sources. Since the development of belief function theory introduced by Shafer in the 1970s many combination rules have been proposed in the literature because in highly conflicting situations the emblematic Dempster's rule generates counter-intuitive and unacceptable results in practical applications. In this work, the Dezert-Smarandache theory (DSmT) will be explored, in particular the PCR5 and PCR6 rules of proportional conflict redistribution, and a simple long-distance pipe leakage monitoring method is developed to help in the development of a method for more complicated situations.","PeriodicalId":360947,"journal":{"name":"International Journal of Process Systems Engineering","volume":"313 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-06-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115557394","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}

Power sharing among MTDC systems involves a priority or sequential procedural problem because of the use of the conventional droop strategy. On the other hand, the use of predefined or constant power sharing fails to identify the available power that can be shared when it is not consumed by another inverter. The proposed strategy addresses these issues through a variety of options. The test system presented in this paper consists of three simulated VSC terminals based on a detailed switching VSC model with two AC voltage levels. The MTDC system has been simulated in a PSCAD/EMTDC environment. The simulation results show a significant decrease in operating costs as well as the ability to provide effective protection with respect to the problem of overloading.","PeriodicalId":360947,"journal":{"name":"International Journal of Process Systems Engineering","volume":"16 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-06-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114332652","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 first two techniques are available in the literature, whereas the third one is a technique proposed in the present paper. The theory and principles underlying each technique are briefly discussed before the applicability of each is validated through a case study in the pulp manufacturing industry. The results of each maintenance technique for replacement decision making are compared and discussed from a practical point of view. The present paper concludes that OBM, the proposed technique, provides a more realistic approach towards replacement decision making compared with the other two techniques for functional failure type component. This conclusion is supported by a review of the entire process of replacement decision making based on four practicability criteria, namely, the basic theory and principle of each technique, data requirements and challenge in data collection, data analysis/modelling, and the decision process. Future research recommendations for the application of OBM are also given.","PeriodicalId":360947,"journal":{"name":"International Journal of Process Systems Engineering","volume":"53 11 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-12-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124645835","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}

With the recent push to implement electric vehicles, it became important to evaluate the current transportation fuelling status and identify best scenarios to move towards greener transportation. This paper presents analysis of hybrid transportation with compressed natural gas as a fuelling option to determine the most effective way to implement regional green transportation. Intelligent modelling and simulation techniques are proposed to model transportation and fuelling process and used as basis for performance modelling and analysis for different scenarios. Compressed natural gas is found to be a superior fuel to gasoline based on given scenario conditions and criteria for regional green hybrid transportation. The proposed scenarios are applied on case studies in Ontario to confirm the high value of compressed natural gas as viable fuelling scenarios.","PeriodicalId":360947,"journal":{"name":"International Journal of Process Systems Engineering","volume":"4 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-12-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129375366","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}

Current HEN design methods use approximate models to improve convergence. This work presents a novel linear rigorous algorithm for computation of mass and energy balances which enables rapid synthesis of optimal HEN structure by using modular size heat exchangers. HEN non-iterative simulation algorithm: 1) solves mass balance equations for the network; 2) computes heat exchanger energy transfer factor which depends only on the current flows through the exchanger and conditions for a typical counter-current heat exchanger; 3) solves linear energy balance given results from 1 and 2. This once-through rapid computation enables network design via differential evolution algorithm by using heat exchangers in modular sizes. Several examples illustrate the algorithm capability to determine the best structures.
