Many new installations will continue to exist behind-the-meter (remain invisible), which poses challenges to the operating utilities for infrastructure and operations planning. This paper presents an approach to estimate the behind-the-meter solar PV size and the battery capacities. The proposed approach is based on energy balancing in buildings, and relies on data that is commonly available with utilities. The proposed approach is validated using a real-world dataset of 716 residential customers from a developed economy. The approach is compared with two baselines used by the studied Utility company. Results from the case study show that in 85% of the cases, the proposed approach has an accuracy of 98% in estimating the rooftop PV capacity (accuracies of baselines were in range 0%-30%). In estimating the battery capacity, the approach's estimates had less than 20% error in 70% of the cases (versus 35% error for baselines). The approach is also capable of discovering battery (dis)charging schedules, which is an additional useful information for utilities.","PeriodicalId":182098,"journal":{"name":"2019 IEEE Power & Energy Society Innovative Smart Grid Technologies Conference (ISGT)","volume":"57 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":"115768620","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}

Conventional direct load control programs are largely insufficient to address these issues. This paper presents results from validation tests of a new approach to demand side management, in which an aggregated fleet of devices is managed as a virtual battery, using principles that are found in communication networks: packetization and randomization. Validation results from a cyber-physical testbed with 5000 devices and a field-trial with 82 customer-owned water heaters show that the packetized virtual battery system can effectively solve a number of different problems. Customer satisfaction survey results illustrate that the system is able to maintain a high level of service quality.","PeriodicalId":182098,"journal":{"name":"2019 IEEE Power & Energy Society Innovative Smart Grid Technologies Conference (ISGT)","volume":"261 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":"122539885","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 integrated current sensor unit incorporates sensing, data processing & storage, and in-field calibration capabilities. A combination of direct-write printing technique and low-temperature curable metallic ink is used to print Ag wires around a $12.5-boldsymbol{mu} mathbf{m}$-thick permalloy film. The overall thickness of the polyimide substrate and permalloy sheet remains well-below $500 boldsymbol{mu} mathbf{m}$ enabling wrap-around sensor functionality. Fused deposition modeling (FDM) additive manufacturing is used to build custom parts for sensor mounting, encapsulation, and an in-field calibration unit using heat and chemical-resistant thermoplastic which responds well to mechanical stress. In the present configuration, the integrated current sensor unit can be powered through USB or 4 AAA batteries to allow data collection and sensor calibration in the field. The flexible current sensor employing a continuous sheet of the permalloy exhibited a well-behaved signal output response at peak current levels exceeding 15A and in the applied ac frequency range of 60 Hz–10 kHz. Overall, the combination of direct-write printing, thin permalloy material, and additive manufacturing technique shows promise for the development of a reconfigurable low-cost current sensor that can be deployed in large numbers at locations of interest to avail the cost and energy-saving opportunities in industrial/commercial and residential applications.","PeriodicalId":182098,"journal":{"name":"2019 IEEE Power & Energy Society Innovative Smart Grid Technologies Conference (ISGT)","volume":"22 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":"129733585","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 proposed approach, the centralized convex optimization problem of a microgrid with distributed energy resources is decomposed into sub-problems solved iteratively by the respective agents in a distributive manner using privacy-preserving asynchronous alternating direction method of multipliers (ADMM) algorithm. In this algorithm, each agent accumulates the sub-system updates from local controllers and only shares partial information with the adjacent agents while minimizing the aggregated operational cost of the microgrid in a cooperative mode. The numerical result shows that the algorithm can reach the convergence very fast under various conditions. The optimality of this algorithm was analyzed briefly and its effectiveness was compared with the synchronous ADMM algorithm.","PeriodicalId":182098,"journal":{"name":"2019 IEEE Power & Energy Society Innovative Smart Grid Technologies Conference (ISGT)","volume":"11 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":"114533906","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}

However, solar PV often appears within distribution systems where existing infrastructure was designed under a central-station paradigm. Fortunately, smart grid technologies can aid integration of distributed energy resources through better characterization of how these resources affect the grid. Using a New York utility service territory as a test bed, we present a data-driven Monte Carlo framework that estimates the maximum installed solar PV capacity at the distribution feeder level subject to existing network constraints. Working with representative days that closely match a feeder's load profile, we probabilistically select PV systems according to current New York trends and stochastically model hourly electricity generation. We found 262,318 kW of solar PV could be added across the entire utility service territory meeting 14.14% of electricity demand.","PeriodicalId":182098,"journal":{"name":"2019 IEEE Power & Energy Society Innovative Smart Grid Technologies Conference (ISGT)","volume":"224 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":"124444015","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}

This paper uses a Monte Carlo simulation to investigate the effect of DR on the loss of load probability in a sequential simulation framework.
