This paper proposes a cooperative game theory-based two-stage approach to effectively determine optimal locations and sizes of DERs. In the first stage, a certain number of candidate locations of DERs are selected based on the equivalent locational marginal costs (LMCs) per unit active power at each bus and the worths (or values) of individual candidate locations and their coalitions are computed. The equivalent LMCs are determined using the weighted average of LMCs for reduced load scenario sets. In the second stage, the Shapley value, one of the solution concepts of cooperative game theory, is used to determine the optimal locations and sizes of DERs. Case studies on IEEE 14-bus and 30-bus systems show that the total cost of generation is reduced after DER placement using the proposed approach as compared to the-state-of-the-art approaches.","PeriodicalId":123077,"journal":{"name":"2021 North American Power Symposium (NAPS)","volume":"18 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-11-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127528257","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 socalled Maximum Power Point Tracking (MPPT) method aims to operate the PV module at its maximum power point (MPP) by matching the load resistance to its characteristic resistance, which changes with temperature and solar irradiance. Perturbation and Observation (P&O) is a popular method that lays the foundation for many advanced techniques. We propose a deep reinforcement learning (RL) based algorithm to determine the optimal perturbation size to reach the MPP. Our method utilizes an artificial neural network-based predictor to determine the MPP from temperature and solar irradiance measurements. The proposed technique provides an effective learning-based solution to the classical MPPT problem. The effectiveness of our model is demonstrated through comparative analysis with respect to the popular methods from the literature.","PeriodicalId":123077,"journal":{"name":"2021 North American Power Symposium (NAPS)","volume":"8 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-11-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123742306","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 develops an estimation method for determining a fixed power factor control setting of a behind-the-meter (BTM) solar PV smart inverter. The estimation is achieved using linear regression methods with historical net load advanced metering infrastructure (AMI) data. Notably, the BTM PV power factor setting may be unknown or uncertain to a distribution engineer, and cannot be trivially estimated from the historical AMI data due to the influence of the native load on the measurements. To solve this, we use a simple percentile-based approach for filtering the measurements. A physics-based linear sensitivity model is then used to determine the fixed power factor control setting from the sensitivity in the complex power plane. This sensitivity parameter characterizes the control setting hidden in the aggregate data. We compare several loss functions, and verify the models developed by conducting experiments on 250 datasets based on real smart meter data. The data are augmented with synthetic quasi-static-timeseries (QSTS) simulations of BTM PV that simulate utility-observed aggregate measurements at the load. The simulations demonstrate the reactive power sensitivity of a BTM PV smart inverter can be recovered efficiently from the net load data after applying the filtering approach.","PeriodicalId":123077,"journal":{"name":"2021 North American Power Symposium (NAPS)","volume":"255 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-11-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114376161","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 method is based on one minus linear correlation and Euclidean pair-wise distance measures to cluster loads that are on the same phase. The phases are assigned to loads based on a majority vote of phase labels within each cluster. The hierarchical clustering methods are compared with other clustering methods such as k-means clustering for various loads connected to different phases. The Electric Power Research Institute's (EPRI) ckt5 test circuit is used to generate a synthetic dataset of single-phase load voltage magnitude measurements. Real power load profiles generated from uniform white noise is used with the OpenDSS software to generate the load voltage magnitude measurements. The accuracy and the running time of the proposed hierarchical clustering are comparable with the k-means algorithm.","PeriodicalId":123077,"journal":{"name":"2021 North American Power Symposium (NAPS)","volume":"102 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-11-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115584034","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 work combines two algorithms found in the literature regarding the power curtailment of PV systems. The first is focused on providing a fast irradiance tracking capability, whereas the second is focused on achieving real-time maximum power point estimation (MPPE) when the system operates in power curtailment mode. By combining both algorithms, a technique providing fast tracking with real-time power reserves estimation is presented. First, a testbed of a two-stage PV system composed by a dc/dc boost converter cascaded with a single-phase inverter is built in Simulink. Next, simulations are carried to match the experimental data from the first algorithm to validate the testbed. Then, the second algorithm is combined with the first to create a testbed with potential to provide power reserves while maintaining fast irradiance tracking. Results demonstrate that the Simulink testbed can match the performance from experimental tests for PV system studies.","PeriodicalId":123077,"journal":{"name":"2021 North American Power Symposium (NAPS)","volume":"36 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-11-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123420617","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}
