In this paper, the long term hydro scheduling problem is solved and used to test novel definitions of hydro-capacities, based on expected cost and cost probability distributions for system operating cost, based on rising load and a within-the-year time distribution of load. The paper expands on previous capacity definitions and tests them numerically in a case study with realistic data from a hydro-dominated system. The principal contribution of this paper are new capacity concepts and practical applications for an example of sizing a given reservoir. The testing is performed using actual data from the Icelandic hydro-dominated power system, with the model HYDOVG delivering optimal schedules for various inflow instances and load cases and using linear programming (LP) CPLEX software to optimize each case and instant.","PeriodicalId":296398,"journal":{"name":"2017 IEEE Power & Energy Society Innovative Smart Grid Technologies Conference (ISGT)","volume":"54 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133735745","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 impulsive and high-power-density characteristics of PEV make conventional assessment methods of load impact unsuitable. This paper proposes an integrated method to investigate the long-term impact of PEV charging on temporal response and depreciation of grid assets in sub-transmission and distribution grid levels (below 69kV). Compared to conventional methods, the proposed method embeds dynamical system models of grid assets in Time-Series (TS) analysis and captures stochastic charging behavior through Monte-Carlo simulation, promising more robust and accurate assessment. Under the proposed method, the Total Cost of Ownership (TCO) of grid assets formulation is re-established. The results of this paper will enable utilities to quantify the capital and operation cost of grid assets induced under various PEV's penetration level and during any time span of interest.","PeriodicalId":296398,"journal":{"name":"2017 IEEE Power & Energy Society Innovative Smart Grid Technologies Conference (ISGT)","volume":"70 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127368273","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 problem is then solved with standard linear programming solvers. The proposed approach was tested using Idaho Power Co. (IPC) system. It allows us to reduce the number of PMUs as compared to conventional techniques while maintaining complete system observability. A fast topological approach was also demonstrated and tested using IPC data in order to analyze the observability of the IPC network.

Distinguishing features of the proposed approach is that it facilitates detection of bad-data in local PMU measurements without requiring a system-wide state estimator. The proposed approach relies on a performance evaluation technique which computes the probability density function (pdf) of the residuals provided by a dynamic state estimator. In the proposed approach it is assumed that there are at least two local PMUs that provide measurements to the dynamic state estimators of a synchronous generator. The proposed approach is implemented using a two-axis model of a synchronous generator with IEEE-Type 1 exciter. The performance of the proposed approach is investigated in the presence of bad-data associated with the measurements provided by the PMUs.","PeriodicalId":296398,"journal":{"name":"2017 IEEE Power & Energy Society Innovative Smart Grid Technologies Conference (ISGT)","volume":"36 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125540405","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 wind turbines have sufficient capacity to support the entire island without using the diesel engines, allowing the formation of an islanded power system completely powered by renewables. The proposed strategy includes use of the flywheel, wind turbines, and diesel generators to attain survivability and resilience. The strategy is challenged and validated against different low to turbulent wind gust profiles and low to peak loading. Multiple permissive-based decoupling schemes, tie-flow controls, and heat load trading features are implemented. The tie-line flow control/heat load trading is operated in tandem with local diesel generators and wind turbines to maintain a minimum flow from the utility.

To achieve demand-following-generation regime, it is important to utilize flexibility of demand by direct or indirect control. It is referred as Demand Response (DR). Indirect control involves incentives or variable prices in different time blocks to bring the aggregated demand at a desired level. In a market scenario, demand and price are mutually dependent variables, i.e., demand can affect the price and vice-versa. In this paper, we present an empirical analysis of demand response based on real time pricing. The analysis is done to study the convergence of the demand in a closed loop market scenario and sensitivity of DR with varying price elasticity.","PeriodicalId":296398,"journal":{"name":"2017 IEEE Power & Energy Society Innovative Smart Grid Technologies Conference (ISGT)","volume":"4 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134554226","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}

An extreme learning machine (ELM) based state forecaster is developed to accurately predict system states (voltage magnitudes and angles) in the near future. Based on the forecast system states, a dynamically weighted three-phase AC OPF problem is formulated to minimize the voltage violations with higher penalization on buses which are forecast to have higher voltage violations in the near future. By solving the proposed OPF problem, the controllable resources in the system are optimally coordinated to alleviate the potential severe voltage violations and improve the overall voltage profile.

In this research, an optimal energy management of a standalone microgrid under different operational modes is studied. The objective of the optimization model is to improve energy utilization efficiency; reduce fuel cost and gas emissions by scheduling productions of energy resources in each hour on the next day. In another word, the problem is modeled as a constrained single-objective programming to minimize cost of power and emission generations. The system is tested under two different operational policies where microgrid power generation sources work with and without battery storage system.

The frequency controller itself is designed using an optimal LQR (Linear Quadratic Regulator) approach whose parameters are obtained using Particle Swarm Optimization (PSO). The utilized isolated smart microgrid comprises different Distributed Generation (DG) units and Renewable Energy Sources (RESs). Implementation of the optimal LQR controller requires a communication network. The key issue in this Networked Control System (NCS) is the transmission of measured data from the multiple sensing agents to the controller. Usually the data is sent in constant intervals which raises energy issues and channel capacity and requires bigger sending rate that will cause more error in the frequency response. The paper proposes different adaptive approaches for determining an adequate sending rate. Simulation results show the effectiveness of the proposed approaches as compared to conventional methods.","PeriodicalId":296398,"journal":{"name":"2017 IEEE Power & Energy Society Innovative Smart Grid Technologies Conference (ISGT)","volume":"33 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122238095","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}
