Several micro-grid test beds in the forms of either hardware or software simulation have been developed around the world.

This micro-grid consists of various fundamental power system components, including two synchronous generators (SG), one fixed speed induction generator (FSIG), and one doubly-fed induction generator (DFIG). In this paper, simulation results of the NTHU micro-grid system in distributed real-time simulation platform OPAL-RT are reported. Dynamical modeling of various distributed generations (DG) will be studied. Control strategies for DGs are verified through simulations on two different scenarios: (1) transition from the grid-connected mode to the islanding mode, and (2) load variation in the islanding mode.","PeriodicalId":330758,"journal":{"name":"IEEE PES Innovative Smart Grid Technologies","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-05-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130879551","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}

We first present an optimal RTP scheme which is based on two-layer optimization processes performed separately on consumer side and retailer side of an electricity network for social welfare maximization. We further proceed to classify consumers based on their load profiles and level-of- participation in demand response program under RTP scheme. The economic benefits of the RTP scheme to different types of consumers are analyzed and compared with those of flat pricing and time-of-use (ToU) pricing schemes. Numerical simulation results demonstrate that the proposed RTP scheme brings economic benefits to all consumers in particular those who are responsive to the price incentive provided by the RTP scheme.","PeriodicalId":330758,"journal":{"name":"IEEE PES Innovative Smart Grid Technologies","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-05-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124106703","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 ultimate objective is to optimally regulate the supply and demand within the micro-grid while ensuring that individual preferences are met and the overall energy consumption is minimized. This article will only focus on the demand management within the community. A simulation environment is developed using GridLAB-D for a baseline and an improved community model. The residential end uses, including electric vehicle charging, are modeled as stochastic and controllable demands. Energy storage capacity is also included. The improved model is used to evaluate different operational alternatives on the basis of individual residential units. Experimental operating conditions are established for the optimization of energy consumption. We show that with properly designed control strategy we are able to reduce the peak load by 8% and hedge against increased EV usage within the community.","PeriodicalId":330758,"journal":{"name":"IEEE PES Innovative Smart Grid Technologies","volume":"93 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-05-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124289361","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 order to analyze the DRCs of industrial electricity consumers in the time of use (TOU) pricing program, a DR model based on the Support Vector Machine (SVM) regression algorism is proposed in the paper. With the model, electricity consumers' daily load arrangement under different price rate (PR) of TOU pricing program could be simulated. Using the simulating data, the electricity consumers' DRCs could be calculated to make further analysis. The work provides reasonably theoretical reference for designing, evaluating and amending current TOU pricing programs and gives an access to quantitively evaluate electricity consumers' DR potential.

A simulation model, which represents the converter of doubly fed induction generator system is built-in MATLAB, and simulation results which are under symmetry grid voltage fault condition are given that illustrate the excellent performance characteristics of the Fuzzy- PI compound control system.

A large number of electric vehicles as distributed energy storage units can feedback to the grid when the grid needs to provide energy and ancillary services. Electric vehicles can either simulate the generator droop characteristic in primary frequency regulation or be based on area control error (ACE) in the power system secondary frequency modulation. At the same time, electric vehicles can be involved in the third frequency modulation based on economic dispatch. In this study, we establish signal area power system model and interconnected two-area model containing V2G and analyze the effects of V2G participation in secondary frequency modulation based on ACE. The results show that V2G can effectively reduce the frequency deviation and tie-line flow deviation, lower system reserve capacity.","PeriodicalId":330758,"journal":{"name":"IEEE PES Innovative Smart Grid Technologies","volume":"42 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-05-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115108006","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}
