In this work, a comprehensive approach is proposed to provide optimal and real-time information toward mitigating wildfire risk in all resilience phases, necessary to decompartmentalize wildfire response. This paper focuses on the optimal routing of the remote monitoring resources for a self-sufficient low-cost wildfire mitigation model (SL-PWR), which utilizes predicted spatio-temporal wildfire probability maps of the utility service area and optimized unmanned aerial vehicle (UAV) monitoring trees to obtain input images for training the SL-PWR modules.

Although power utilities have spear-headed several initiatives, the need for a comprehensive risk management approach that can be easily integrable into current power utility methods and operations cannot be overemphasized. This work proposes a self-sufficient low-cost wildfire mitigation model (SL-PWR), a tool that automates wildfire risk reduction by intelligently functioning from the pre-wildfire phase to prevent wildfires, through the wildfire progression phase for very early detection, to system restoration after damages. Hence, the SL-PWR addresses endogenous and exogenous wildfire mitigation and risk reduction in all system resilience phases, de-compartmentalizing wildfire response. The proposed SL-PWR tool advances on spatio-temporal wildfire detection through data-driven optimization and automation to provide accurate quantitative and visual real-time critical wildfire information to infrastructure operators and emergency management teams. This paper, part of a series, presents the design and development of the SL-PWR’s functional processes, which further enables optimal monitoring for accuracy and rapidity in response, as well as economic decision making of the utility. Results using publicly sourced data from a synthetic utility service area show the performance of the SL-PWR is accurate, enables rapidity, and improves situational awareness during wildfire threats.","PeriodicalId":56187,"journal":{"name":"IEEE Open Access Journal of Power and Energy","volume":null,"pages":null},"PeriodicalIF":3.8,"publicationDate":"2023-11-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://ieeexplore.ieee.org/stamp/stamp.jsp?tp=&arnumber=10332241","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139041229","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This paper proposes a real-time voltage control method based on deep reinforcement learning (DRL) that continuously regulates the excitation system in response to system disturbances. Dynamic performance is considered during control by incorporating the voltage dynamics data that influence the practical power grid operation. The proposed approach utilizes the deep deterministic policy gradient (DDPG) algorithm, capable of handling continuous action spaces, to adjust the voltage reference of the generator excitation system in real time. To analyze the power system dynamic process, a versatile transmission-level power system dynamic training and simulation platform is developed by integrating the power system simulation software PSS/E and a user-written DRL agent code developed in Python. The platform facilitates the training and testing of various power system algorithms and power grids in dynamic simulations. The efficacy of the proposed method is evaluated based on the developed platform through extensive case studies on the IEEE 9-bus system and the Texas 2000-bus system. The results validate the effectiveness of the approach, highlighting its promising performance in real-time control with respect to dynamic processes.","PeriodicalId":56187,"journal":{"name":"IEEE Open Access Journal of Power and Energy","volume":null,"pages":null},"PeriodicalIF":3.8,"publicationDate":"2023-11-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://ieeexplore.ieee.org/stamp/stamp.jsp?tp=&arnumber=10316276","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135612458","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Grid voltages are known to be time-varying and can contain distortions, unbalances, and harmonics, which can lead to poor tracking and high total harmonic distortion (THD). The proposed adaptive control structure addresses this issue by enabling or disabling harmonics compensation blocks based on the grid voltage’s characteristics. The DSO framework is implemented to generate an equivalent mathematical expression of the grid voltages, which is then incorporated into the RMRAC-based controller. The controller is then able to reconfigure itself to adequately compensate for high harmonics present in the grid, reducing computational complexity and improving performance. A controller-hardware-in-the-loop (C-HIL) environment with a Typhoon HIL 604 and a TSM320F28335 DSP is implemented to demonstrate that the proposed RMRAC-based structure with DSO outperforms both the same adaptive structure without DSO and a superior RMRAC-based controller.

When considering multiple-input multiple-output systems most traditional stability techniques are reliant on the diagonal dominance of the studied system. Therefore, a rating of diagonal dominance is proposed based upon the correlation coefficient between row and column in the impedance matrix. This provides a scale that ranges from off-diagonally dominant (−1) through uniformly distributed (0) and up to diagonally dominant (1) across a range of frequencies. The scale is used to specify which control structures can be considered as diagonally dominant at certain frequencies and which control components have the greatest effect on the rating. A direct relation is found between system exhibiting a diagonal dominance rating of 0.7 and above and the efficacy of traditional stability margins. Traditionally strong systems with low network impedance where controllers can be tuned conservatively exhibit high degrees of diagonal dominance and can be analysed quickly with traditional margins with minimal error. For systems exhibiting a lower rating, disk margins are explored as an alternative which offer greater accuracy. Additionally, more realistic perturbations of gain and phase occurring simultaneously in multiple channels can be considered which is more applicable for the modern electricity network with a high penetration of grid-connected converters.","PeriodicalId":56187,"journal":{"name":"IEEE Open Access Journal of Power and Energy","volume":null,"pages":null},"PeriodicalIF":3.8,"publicationDate":"2023-09-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://ieeexplore.ieee.org/stamp/stamp.jsp?tp=&arnumber=10266916","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"109157721","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To handle it, this paper proposes an online localization method for cable partial discharge signals that is suitable for practical engineering applications, based on the double-end localization method. The proposed method uses an improved generalized correlation algorithm to estimate the signal time delay, and takes into account the wave speed uncertainty of the local discharge signal. To improve local localizing accuracy under multiple localizing samples, a trimmed-mean data filtering speed algorithm is employed. Simulation and experimental results demonstrate that the proposed method effectively enhances time delay estimation accuracy and reduces localization error, even under complex electromagnetic noise environment and restricted sampling rates of detection equipment, when compared to traditional time delay estimation localization methods. The positioning accuracy of partial discharge in field experiments reached 97.43%-99.89%, which meets actual engineering requirements.","PeriodicalId":56187,"journal":{"name":"IEEE Open Access Journal of Power and Energy","volume":null,"pages":null},"PeriodicalIF":3.8,"publicationDate":"2023-09-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://ieeexplore.ieee.org/stamp/stamp.jsp?tp=&arnumber=10261236","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"109157720","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Only a single measurement is needed while the machine is in saturated mode. However, this destructive test can significantly reduce the lifetime of the stator winding. Moreover, determining the equivalent diagram in the q-axis is more complicated and is often not performed. DC-decay tests are low-power alternatives that allow for the determination of the equivalent diagram in both axes without damaging the machinery. Until recently, they required the rotor to be aligned with the axes, which is not feasible in large power plants. A recent breakthrough eliminated the need for rotor alignment by proposing a DC-decay test that can be performed with the rotor in any position. However, numerous independent measurements are needed to obtain the equivalent diagram in both axes. This paper addresses the question of the minimum number of independent measurements needed for the DC-decay test to be practical for industrial use. Around 10 measurements are sufficient for reasonable precision, while 5 of high quality are sufficient using the symmetry of the root locus. Finally, a comparison against the short-circuit test shows that the DC-decay test is a valid alternative.","PeriodicalId":56187,"journal":{"name":"IEEE Open Access Journal of Power and Energy","volume":null,"pages":null},"PeriodicalIF":3.8,"publicationDate":"2023-09-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://ieeexplore.ieee.org/stamp/stamp.jsp?tp=&arnumber=10243408","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"62828382","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

These connected between distribution feeders may regulate the active power flow in a controlled manner and contribute to the network voltage support. However, the power losses of these devices can be a limiting factor of some functionalities. This paper integrates a detailed power loss model of several flexible link topologies for Optimal Power Flow algorithms with the aim of evaluating its impact on the functionalities of these devices. In this way, it is possible to benchmark the performance of different DC and AC flexible links in a quantitative manner by means of some key performance indexes.

Electricity-supply reliability and resilience can be enhanced by customers having on-site energy storage, which supplements electricity-system supply. This paper proposes a two-stage stochastic optimization model that can be used in a rolling-horizon fashion to schedule such use of energy storage. We demonstrate the model with a case study that combines electricity-supply-reliability data for a real-world electric utility, survey data regarding residential customers’ willingnesses to pay for backup energy during electricity-supply disruptions, and a highly resolved Markov chain model of building-occupant behavior and associated electricity use that is calibrated to census data. We find that the low probability of an electricity-supply disruption occurring during any given time-step limits the charging of the energy storage in anticipation of possible disruptions. We demonstrate two approaches to reduce this myopic use of energy storage. Our case study shows that penalty parameters can be used to control the conservatism of the model in using as opposed to retaining stored energy during an electricity-supply disruption. Overall, we show the viability of on-site energy storage to enhance electricity-supply reliability and resilience and the feasibility of our model and algorithm for real-time control of energy storage for such a real-world application.","PeriodicalId":56187,"journal":{"name":"IEEE Open Access Journal of Power and Energy","volume":null,"pages":null},"PeriodicalIF":3.8,"publicationDate":"2023-07-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://ieeexplore.ieee.org/stamp/stamp.jsp?tp=&arnumber=10196362","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"62828438","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
