The protection blindness of the OCP has been demonstrated through novel mathematical formulation to quantify the percentage of the protection blindness for different type of distributed generation (DGs) units and for their varying penetration levels. In addition, this issue has been realistically analyzed for the different fault impedances to examine its impact on the traditional OCP system. A mitigation strategy has been proposed to overcome the SD issue of the OCP protective devices (PDs) for a robust detection and clearance of electrical faults by the OCP devices without the need for a costly upgradations of the protection system. This protection blindness issue has been explored and the mitigation strategies have been tested for both synchronous and inverter based DGs using the IEEE standardized test feeder. The results prove the effectiveness of the proposed mitigation strategy for their practical applications and suitability to improve the grid resilience.","PeriodicalId":115239,"journal":{"name":"2020 IEEE Industry Applications Society Annual Meeting","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-10-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131390362","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}

Microgrids can be effective in meeting local load requirements as well as in improving the power quality and stability in a modern power distribution system. Multiple microgrids can also be operated in a coordinated manner as a cluster, to improve the resiliency of the power distribution system. In the event of an outage caused by a transmission system failure, the microgrids in a cluster can use their distributed generation capacity and energy storage resources to recover and extend power availability to the critical loads in the system. In this paper, an illustrative cluster of two microgrids based on the IEEE 13-bus model with DERs has been used, to demonstrate the operation of the concept using real-time simulations. Using real-time simulations, capabilities such as switching reconfiguration following faults, identification of optimal DER placement for effective power quality management, and power electronic controller validation have been demonstrated. For the two-microgrid cluster, this paper also presents improvements in load voltage quality and extension of service availability by shedding non-critical loads.","PeriodicalId":115239,"journal":{"name":"2020 IEEE Industry Applications Society Annual Meeting","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-10-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130129820","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}

Multiple voltage disturbances in distribution network like voltage sag, swell, voltage imbalance, and distortions are taken into consideration for compensation using DVR. The CVSSLMS has the combined features of both Normalized LMS (NLMS) and LMS algorithms such as effective transient response and reduced steady state error, respectively. In internal structure of algorithm, PI controllers are used as error regulator to regulate dc and ac bus voltages through error minimization technique. The PI controller gains are tuned through an optimization algorithm named as ant-lion optimization (ALO) algorithm. The added feature of ALO is the avoidance of local optimum. With this control algorithm, the performance of three phase DVR is simulated for the aforesaid disturbances using MATLAB/Simulink model. It is also experimentally tested using DSP (Micro Lab Box, made by Free scale QorlQ P5020) in three phase distribution networks.

This is because of the varying power output of solar PV due to the changing weather conditions and the controls required for a three-phase system. A system that operates induction motor loads, such as in the water pumping plant, increases this difficulty due to their high starting currents and power requirements, which can cause large voltage dips in a grid-connected system, and can have an even larger impact on isolated ones. A battery energy storage system (BESS), consisting of a large lithium-ion battery, a bi-directional dc-dc converter and a bi-directional dc-ac converter is considered in this paper to normalize the output power. A model is developed to accurately simulate the motor loads and the control strategies to operate the system to consume zero grid power at all times. These strategies are designed to limit the transients in the system, as well as to mitigate voltage dips and swells to create a more robust micro-grid. The proposed strategies are then applied for use in a water pumping plant equipped with solar PV and BESS and the simulation results show that the proposed strategy is effective in ensuring that the plant can maintain a zero grid power consumption when sufficient capacities of the solar PV and BESS are available that can be allocated to generate and store the required energy to meet the varying load.","PeriodicalId":115239,"journal":{"name":"2020 IEEE Industry Applications Society Annual Meeting","volume":"111 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-10-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131676434","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}

To ensure the power system continues to function adequately, some grid operators require an inertial response from the wind turbines. Synthetic inertia, or the combined inertia from individual wind power turbines in a wind farm, can provide a measured inertial response to the system under various wind power penetration levels. However, the response to the system due to the synthetic inertia from the turbines may not be adequate to assist in the stability of the system due to its rapid response time, usually in the range of a couple of seconds. In this paper, effective load modelling is merged with the effects of synthetic inertia to discover what role these two methods can have on stability in the power system. The Alberta interconnected electric system (AIES) is used to test the proposed hybrid model. Alberta is an energyonly deregulated market. It is expected a higher volume of renewable energy will be added to the power systems everywhere including the AIES. The increase in renewable penetration may result in transient stability challenges. This paper explores how synthetic inertia and load modelling can facilitate a system stability opportunity. Further, the paper examines how synthetic inertia and load modelling can perform under various wind power penetration levels within the Alberta power system. Finally, the response of the inertial model is demonstrated through detailed simulations.","PeriodicalId":115239,"journal":{"name":"2020 IEEE Industry Applications Society Annual Meeting","volume":"23 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-10-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115887454","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 flexible excitation system of the synchronous generator is a novel structure with full-controlled devices, which has two damping channels. One is controlled by PSS, and another can be controlled by the reactive power damping controller (RPDC) to improve the damping over the lower-frequency range. A novel structure, avoiding the limitation of the excessive higher-frequency gain on lower-frequency damping, is adopted in RPDC. The parameters design method of the flexible excitation system is proposed. A SMIB system is established in RTDS (real time digital system), and various oscillation frequencies (i.e. 1.2 Hz, 0.5 Hz, and 0.3 Hz) are obtained by adjusting TJ. The comparisons between the flexible and conventional excitation system show that the flexible excitation system can provide more damping to reduce the steady time, decrease the oscillation amplitude, and improve the power system stability over the full frequency range of LFO, especially over the lower-frequency range.","PeriodicalId":115239,"journal":{"name":"2020 IEEE Industry Applications Society Annual Meeting","volume":"52 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-10-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114776466","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}
