But, the high initial installation cost, requirement of suitable places and the anticipated immense load on the grid during peak time hinder to elongate the charging station network, especially in urban areas. As a consequence, the bidirectional energy transferring capability between vehicle to vehicle (V2V) may act as an auxiliary solution to charge an EV at any place and at any time without leaning on a permanent charging infrastructure. Here in this work, we assume a company having a number of V2V enabled charging trucks equipped with a larger battery and a fast charger to charge a number of EVs at some particular parking lots. The company intends to maximize the served number EVs, when an EV should be considered as served if it would be fully charged during its declared charging window. All the charging requests are assumed to be received before the time horizon and we also consider that all trucks should return to the depot after serving EVs. We formulate an integer linear program (ILP) to maximize the number of served EVs by determining the optimal trajectory of each truck. The problem is formally proved as NP-hard and due to its larger computational time, we also propose three different heuristic algorithms: 1) Strictest Window Shortest Path First (SWSPF), 2) Smallest Demand Shortest Path First (SDSPF) and 3) Earliest Arrival Shortest Path First (EASPF). The performance of these three algorithms are examined in detail and finally, SDSPF shows the better performance and its performance is closer to the optimal solution.","PeriodicalId":106476,"journal":{"name":"2020 IEEE Power & Energy Society General Meeting (PESGM)","volume":"252 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-08-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115560979","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 the conventional EMT simulator, the time-step is fixed, which may lead to inefficiencies when the time constants of the system change. The adaptive time-stepping (ATS) method can efficaciously solve this problem; however, the ATS schemes for the universal transmission line model (ULM) and universal machine (UM) model remain to be investigated. This work derives the ATS models for ULM and UM, and the proposed ULM model is more stable than the traditional model. Both ATS models are emulated on the parallel and pipelined architecture of the FPGA. The proposed subsystem-based ATS scheme and the local truncation error (LTE) based time-step control enable the large-scale systems to be simulated in real-time and “faster-than-real-time” modes. The IEEE 39-bus system with ATS models was emulated on two interconnected FPGA boards, and the emulation results compared with PSCAD/EMTDC and fixed time-stepping (FTS) hardware emulator verified the effectiveness of the proposed models and showed that the LTE of ULM and UM can be reduced by 76.5% and 62.0% respectively compared with the FTS simulation.","PeriodicalId":106476,"journal":{"name":"2020 IEEE Power & Energy Society General Meeting (PESGM)","volume":"114 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-08-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116106307","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}

Such sources usually have very small or no rotating inertia, thus resulting in a significant reduction in the overall system inertia. Low inertia can lead to loss of synchronism even for small disturbances, cascading failures, and blackouts. Virtual Synchronous Generators (VSG) have the potential to compensate for the reduced inertia due to the high penetration of renewable energy sources and DGs. However, determining the minimum sizes of VSG to maintain power system stability is a challenging task. In this paper, a probabilistic approach is proposed to determine the sizes of VSG to enhance the dynamic performance of power systems under various loading and failure conditions. In the proposed approach, Monte Carlo simulations are performed to emulate the variability of system loads and uncertainties of fault clearing times. The time domain simulation approach for multi-machine systems is performed to determine the required sizes of VSG. The proposed method is demonstrated on the reduced Western Electricity Coordinating Council 9-bus transmission system. The results show that the determined sizes of VSG are sufficient to maintain the stability of low-inertia power systems.","PeriodicalId":106476,"journal":{"name":"2020 IEEE Power & Energy Society General Meeting (PESGM)","volume":"31 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-08-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114148201","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 excess storage, thermal, and generation capacity can be used to develop new markets for ancillary services such as peak reduction, voltage and frequency support, or load flattening. Widespread participation in these markets will make the power grid more resilient. However, widespread participation in these markets will require a simple and intuitive control over the excess capacity by the building occupants. Most importantly for adopting these technologies, participation in these markets should not require sacrificing occupant comfort. Many of the proposed control and optimization technologies for supplying the ancillary services do not explicitly incorporate occupant comfort into their models and when they do, generally utilize a rigid constraint on the indoor air temperature set a priori. This reduces flexibility in using excess thermal capacity. It also cannot take into account uncertainties in local factors that affect thermal comfort such as clothing insulation or relative humidity. In this paper, we present and justify some assumptions that simplify the standard predictors of thermal comfort. We also develop a regression model of the thermal comfort that is linear with respect to the indoor air temperature. Next we develop the concept of thermal comfort variation that eliminates the dependence of the thermal comfort on uncertain thermal comfort factors. Then, we present a quadratic program utilizing the thermal comfort variation in both the objective function and as a constraint. Finally, we show the results of a time-of-use cost optimization that utilizes the simplified thermal comfort model.","PeriodicalId":106476,"journal":{"name":"2020 IEEE Power & Energy Society General Meeting (PESGM)","volume":"13 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-08-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"117010155","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}
