In the CPS, a crucial problem for the evaluation of control systems to face disturbances/faults is transmission time delay in the communication network. In this paper, a hybrid simulation model is established to simulate the operation of CPS, and the time delay is considered in the design process of model predictive control (MPC) based low-frequency oscillation (LFO) damping controller. In the proposed model, the IEEE benchmark two areas interconnected power system with a flexible ac transmission system (FACTS) device is established in the MATLAB/Simulink environment, and the information systems with advanced cyber control center is established in the Microsoft Visual Studio environment. The utility communication network of 3G and fiber optic access is adopted to transmit operation and control data between the aforementioned environments, and the communication time delay is considered sufficiently. In this way, a CPS closed- loop control is formed. Finally, a case study is used to validate the established hybrid simulation model as well as the performance of cyber control center.","PeriodicalId":439089,"journal":{"name":"2015 IEEE PES Asia-Pacific Power and Energy Engineering Conference (APPEEC)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129597274","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 modern transmission system planning, it is necessary to consider the accommodation capability of renewable energy generation, in addition to the traditional requirement for power system reliability. Given this background, a bi-level transmission system planning model is presented for this purpose with transmission investment costs, load shedding costs, abandoned wind power costs as well as relevant operating constraints considered. In the upper level, the objective is to minimize the sum of annual investment cost and the expected value of annual economic loss of shedding load and wind energy abandoned for given scenarios. In the lower level, the objective is to minimize the sum of economic loss of shedding load energy and wind energy abandoned for each scenario. These two levels are implemented interactively and iteratively, and the optimal transmission system planning scheme will ultimately be attained. The upper level model is described as a mixed-integer optimization problem, and solved by the well- established particle swarm optimization algorithm; the lower level model is formulated as a linear programming problem, and solved by the linear programming solver ILOG CPLEX. Finally, the essential characteristics of the proposed models and adopted algorithms are demonstrated by a modified 18-bus sample power system.","PeriodicalId":439089,"journal":{"name":"2015 IEEE PES Asia-Pacific Power and Energy Engineering Conference (APPEEC)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130065867","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 this context, a bi-level linear programming model is established for an aggregator of day-ahead energy acquisition in a smart distribution system with DR into consideration. The outer-level simulates the decision-making process of an aggregator who endeavors to maximize its profit by optimal energy acquisition and flexible energy consumption strategy. The decision-maker of the innerlevel is DSO, who takes the responsibility for the economic dispatch of the distribution system and determines load interruptions systematically. A highly efficient commercial solver CPLEX is utilized in the MATLAB environment to solve the developed model.

The proposed approach considers two well-known demand side management techniques, namely peak shaving and valley filling. This is done by incentivizing consumers by magnifying price difference between peak and off-peak hours. The usefulness of the suggested method is then investigated by its combination with an electric vehicle optimal scheduling methodology which captures both economic valuation and grid technical constraints. This case is chosen in this study to address network congestion issues, namely under-voltages and overloading which are foreseen as major issues in the distribution system in the coming years. Simulation results demonstrated that the proposed methodology can successfully shift load from peak to off-peak hours, thereby letting higher penetration of EVs in a given distribution feeder.","PeriodicalId":439089,"journal":{"name":"2015 IEEE PES Asia-Pacific Power and Energy Engineering Conference (APPEEC)","volume":"58 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127081802","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}

Several pilot projects are ongoing in the United States. The stable electricity network is important for national security. Fluctuating frequency can be balanced by stabilising generation and load to equal. Power stations transfer electricity through substations to military bases. In network failure situation, military bases can form islanded microgrid. General purpose vehicles can provide V2G services to the microgrid. While electricity price is varying during the time, V2G can provide profit by charging during lower price and discharging during higher price.

Most of LLC converter design starts with LLC parameters calculation. The magnetics are then designed to match the requirements. However, this is not always the most optimized result as the implemented magnetics does not operate at maximum efficiency. Therefore, this paper proposes systematic LLC converter design procedures to deal with this problem. A systematic approach of the magnetics design was conducted, and the introduced methodology is particularly suitable for LLC converters used in solar photovoltaic (PV) energy storage systems. A 350 W LLC converter example was examined and demonstrated. The efficiency performance is very consistent across the operating frequencies, in which the efficiency variation is less than 1.5%.","PeriodicalId":439089,"journal":{"name":"2015 IEEE PES Asia-Pacific Power and Energy Engineering Conference (APPEEC)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128197510","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}
