The main goal of the proposed method is to reduce losses of drivetrain devices. The power sources considered in this work are proton exchange membrane fuel cell and lithium-ion battery while the main power consumers are induction motors driven propulsion system. Both sources and consumers are connected to a common DC bus through power conversion devices. In the proposed method, the DC bus voltage level is controlled according to the loading of the fuel cells. By controlling the DC bus voltage, it allows operation of fuel cell DC/DC converter in freewheeling mode which significantly reduces the converter losses. In addition, this approach is also expected to reduce the motor and battery drive losses. Feasibility of the proposed operation method and loss calculations are presented on a real-time hardware-in-loop simulator consisting of real control units and virtual power device models.","PeriodicalId":365986,"journal":{"name":"2019 IEEE Power and Energy Conference at Illinois (PECI)","volume":"105 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-04-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130655620","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}

They are commonly used to protect premises such as buildings, cattle, large farm areas and international borders. As grid supply may not be available in remote areas, diesel generators are mostly used for energizing the fence. But transportation of diesel to remote areas is often expensive and also a difficult task. However, remote areas often have renewable energy sources. This paper proposes a high-power electric fence energizer using standalone PV generators for remote areas. The proposed energizer is based on standalone PV system with battery backup and Marx generator circuit with high gain resonant converter. An energy management system (EMS) has been implemented for efficient operation of the energizer and proper utilization of solar and battery power. The performance of the proposed energizer has been evaluated for different load and source conditions. The proposed fence energizer can be used to cover large fence areas.","PeriodicalId":365986,"journal":{"name":"2019 IEEE Power and Energy Conference at Illinois (PECI)","volume":"8 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-04-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126545635","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}

For this reason, Maximum Power Point Tracking (MPPT) algorithms are implemented to help PV systems operate at their optimal conditions, hence maximizing the PV systems output power. These techniques adjust the current and voltage parameters of a PV system to extract the maximum power. This paper presents a comparison between analytical exponential and fractal mathematical PV models used to derive the Linear Reoriented Coordinate Method (LRCM) and the Integral Mean Value Method (IMVM). These two approaches are used to obtain the optimal conditions for the PV system, yielding the utmost available power.","PeriodicalId":365986,"journal":{"name":"2019 IEEE Power and Energy Conference at Illinois (PECI)","volume":"56 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116701341","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}

As one means of examining the effects of V2G in a system, V2G is incorporated into Emission-constrained Dynamic Economic Dispatch (DED). To cope efficiently with the complicated problem of V2G with DED, Model Predictive Control (MPC)-based approach is leveraged.

Developments in smart grid devices and communication protocols are advancing the power system domain but are also introducing new cyber attack vectors.

Cryptography is a powerful tool that can be leveraged to protect DER systems and their critical information. This paper discusses prominent methods of cryptographic authentication and encryption that can be used to secure DER communications. Specific considerations and recommendations for applying cryptography to DER systems are provided, including system design constraints and system impact.

To improve grid performance, DERs can be utilized to provide important support functionality, such as supporting frequency and voltage levels, especially if they are assisted by communication schemes as part of an advanced distribution management system (ADMS). Unfortunately, such connectivity and grid support functionality also creates additional cyber security risk with the potential for degradation of grid services, especially under conditions with high amounts of distributed generation. This paper will first discuss the communications needed by DERs to support system and interoperability objectives, as well as the security requirements and impact of securing these communications. Some common security mechanisms are discussed in relation to DERs, and a simulated 15-bus model of a distribution feeder is used to demonstrate aspects of the DER communications and impact to grid performance. These results help to advance understanding of the benefits, requirements, and mechanisms for securely implementing DER communications while ensuring that grid reliability is maintained.","PeriodicalId":365986,"journal":{"name":"2019 IEEE Power and Energy Conference at Illinois (PECI)","volume":"25 3 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125675388","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}

Here, in this work the maximum achievable bandwidth is obtained based on their transfer functions. Alongside, IMC based PID controller designed which is having some prominent features like any bandwidth can be achieved (up to maximum achievable bandwidth) and the PID parameters, filter coefficient (λ) are obtained directly without any assumptions.

The MDCT uses the high frequency transformer to transfer energy, which can reduce the size of the system, but this will generate more switching loss. The basic operation principle of the MDCT under quasi square wave modulation strategy was analyzed firstly. On this basis, this paper proposes a soft-switching operation scheme which can effectively reduce the switching loss for the system. The soft-switching condition and range of MDCT were analyzed and derived. Furthermore, a capacitor voltage-balancing strategy was presented in the MDCT, which can reduce the number of sensors and the cost of the system. Finally, the effectiveness of the theoretical analysis and the overall control strategy have been validated by the simulation results in MATLAB.","PeriodicalId":365986,"journal":{"name":"2019 IEEE Power and Energy Conference at Illinois (PECI)","volume":"21 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123996424","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}
