As DERs continue to proliferate, more complete models will be required to study the dynamic interactions between the electric power transmission and distribution systems. To address this need, results from a study are presented concerning the new supporting role of large, fossil-based generators in a power system with an increased level of renewable energy (distributed in particular). This work considers the transmission and distribution system interplay and it contributes to the establishment of fair and transparent operational and regulatory criteria to ensure sustainability and resiliency in power grids with increased levels of renewable energy penetration.","PeriodicalId":127111,"journal":{"name":"2018 IEEE Conference on Technologies for Sustainability (SusTech)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131210938","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}

In Nigeria, data transferring via wireless is made available through network service providers such as MTN Nigeria, Glo, Airtel, Etisalat and the like. Over the years, users of these network service providers have greatly increased most especially MTN Nigeria. Due to the increase in number of suscribers this has led to some issues in the system such as crosstalk, echo, and signal loss among others which in turn causing discomfort to the users. The MTN network provider company was investigated, traffic data of the network elements collected were from OMC measurement (BSC and MSC) using some predefined algorithms, that consists of counter. The study revealed that MSC route 11(0), has the highest calls attempt with a percentage of 18.7% during the Busy Hour Traffic (BHT), The route with the lowest calls attempt, was MSC route 17(11) having percentage 1.3%. Route BSC 9 has the highest Grade Service with a percentage of 15.4%, while Route MSC 17(11) has the lowest Grade of Service with a percentage of about 0.4%. MSC 17 (11) and MSC 16 (1) have the highest Call Completion rate having a percentage of 13.3% while BSC 9 route with the lowest Call Completion Rate. The route with the highest TCHs Utilization Rate is MSC 17(11), while BSC 10-3(9) has the lowest TCHs Utilization is having a percentage of 7.3%. The study showed that the higher the number of subscribers on the route, the higher the grade of service. Therefore, to ensure efficient grade of service and maintain good network sustainability, network provider should avoid overcrowding of subscribers on their bandwidth. Also, effort should be made by this mobile communications operator to increase the bandwidth and reduce the TCHs Utilization rate, so as to reduce the error messages received by their subscribers.","PeriodicalId":127111,"journal":{"name":"2018 IEEE Conference on Technologies for Sustainability (SusTech)","volume":"12 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115035438","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}

Built upon DC optimal power flow model in previous studies, this paper extends the model to two-sided markets with uncertainties in both generation and load. The convergence of the solution to the efficient Nash equilibrium is discussed and improved, which enables further studies on the dynamic behavior of the mechanism under different levels of renewable penetration and different trading schedules (day-ahead or hour-ahead). In addition, this work shows that by adding ramp rate constraint on actual generation powers, the mechanism can embrace higher uncertainties while maintaining grid reliability.","PeriodicalId":127111,"journal":{"name":"2018 IEEE Conference on Technologies for Sustainability (SusTech)","volume":"47 3","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"120906013","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}

Existing batteries do not have sufficient endurance or effectiveness, so electric-only cars are not capable of competing with current advanced vehicles. On the other hand, plug-in hybrid electric vehicles (PHEVs) have demonstrated their efficacy as attainable, short-range technology choices capable of competing with conventional vehicles. The study proposed in this paper performed reliability assessments of existing power system infrastructures at several PHEV penetration rates. Reliability indices, as numerical variables, can be represented simply as penalty costs for intermission and loss of energy. In the study, several PHEV penetration levels were simulated, and the loss of load probability (LOLP) index was calculated to consider the influence of PHEVs on the reliability of power networks. Furthermore, the minimum generation adequacy of the generation units was evaluated. The results indicated that the infrastructures of our current power systems are not sufficiently strong to handle these increased penetration rates.","PeriodicalId":127111,"journal":{"name":"2018 IEEE Conference on Technologies for Sustainability (SusTech)","volume":"22 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121713251","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}

A loss of synchronization is generally the result of instability. The angle of the rotor in a generator depends on the mechanical power and electrical power. The output power of a synchronous machine is linked to the mechanical torque, which is central to the angle stability of rotor. Therefore, maintaining synchronization in the presence of disturbance is the goal in power generation. In this paper, the transient stability of a power system is investigated by solving the swing equation using the particle swarm optimization (PSO). The investigation is carried out for the swing equation in terms of angle stability during the normal operation and after the fault occurs. Single machine and two-machine power systems are considered in this study. The obtained results show satisfactorily approximation solution for the swing equation. The proposed method introduces a similar and better solution compared to the other conventional numerical methods.","PeriodicalId":127111,"journal":{"name":"2018 IEEE Conference on Technologies for Sustainability (SusTech)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115995367","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}

It is usually called Power Purchase Agreements (PPA) in the Power sector. It is a relatively new delivery method in infrastructure project. It is an updated version of the Build Operate Transfer (BOT) delivery method. Renewable energy PPA are very common because of the high construction cost. They have low operation and maintenance cost which make the overall life cycle cost is low. It gives a way for the developer to get their investment back with a reasonable profit. It helps the owner get the power with low or no initial cost. The risks associated with the PPA method are different from traditional delivery methods. Identifying and understand such risks is a key in the success of PPA projects. It can make such method a viable option to many countries.

With the growth of vehicle electrification, internal combustion engines have become more efficient but not nearly enough. The current trajectory of vehicle development is directed toward battery powered vehicles. This can be seen in the rising production of battery electric vehicles (BEV) and hybrid electric vehicles (HEV). Energy storage system (ESS) viability is a major hurdle being faced by vehicle manufacturers and improving ESS efficiency is the subject of this research paper. More specifically, power loss in the ESS will be reduced through control of the DC/DC converter setpoint voltage. The goal of this research is to show that a variable DC/DC setpoint voltage would allow the system to use power more efficiently by online matching of the system’s real-time power needs. This goal shall be met by testing a model predictive control-based power management strategy in software in the loop (SIL) and then implementing this strategy in hardware in the loop (HIL) using a controller and real-time simulator. This paper builds and improves upon research from a previous manuscript “MPC -based power management strategy to reduce power loss in energy storage system of HEV” [1] with the addition of ESS model system constraints to the ESS model.","PeriodicalId":127111,"journal":{"name":"2018 IEEE Conference on Technologies for Sustainability (SusTech)","volume":"81 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126224715","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 solutions that is found until now are to use renewable energy resources, electric vehicles and improvement in energy efficiency. A microgrid which is an interface between distributed renewable resources and the utility grid is one and reliable way to make use of renewable resource like; PV and wind and is also able to operate both in grid-connected and stand-alone modes. The concept of microgrid is only possible because of rapid development of fastacting power electronics devices. The focus of our research is to develop a hierarchical control strategy for the modular microgrid system by optimally splitting (sharing) the power between energy storage system modules and the utility grid in such a way to reduce the total cost of the electricity (in connected mode). This can be achieved by performing iterations through planning high level algorithm (e.g. a dynamic programming based algorithm) and a local low level algorithm (e.g. model predictive control based algorithm).","PeriodicalId":127111,"journal":{"name":"2018 IEEE Conference on Technologies for Sustainability (SusTech)","volume":"12 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125307572","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}
