Efforts has been made to address this challenge. The solutions generally fall into two categories: centralized and distributed solution. Comparing with centralized EMS, distributed EMS is commonly considered as a more promising and reliable approach. Nonetheless, the current microgrid reliability research are focused on the physical layer of microgrid, such as overhead lines, transformers, circuit breakers and the DER device itself. The reliability analysis that considers controller failure and EMS framework are not reported in current publications. In this paper, a general reliability assessment methodology based on Monte Carlo simulation is presented to assess the reliability of both centralized EMS and distributed EMS in islanding microgrid. Different performance metrics such as system-average-interruption-frequency-index (SAIFI) and expected-energy-not-supplied (EENS) are used to quantify and evaluate the reliability. Simulation results indicates that using the same controller, the microgrid with distributed EMS is able to achieve better reliability indices, and the distributed EMS can achieve same level of reliability using less reliable controllers.","PeriodicalId":296428,"journal":{"name":"2017 North American Power Symposium (NAPS)","volume":"25 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122429623","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}

One of the LQR control design challenges is the state variables weighting matrix, which has lack of systematic method. The new consideration, that determines the LQR state weighting matrix, is based on the trajectory sensitivity analysis (TSA). TSA method solves the system differential algebraic equations to get the sensitivity of state variables and outputs to the system parameters. In this paper, the sensitivity of state variables to the DFIG voltage control input parameter is used to catch the state weighting matrix. The state weighting matrix is considered based on the infinity norm throughout the time series simulation. The proposed weighting matrix is compared with two of the common methods that used in literature using a modified two-area power system. Simulation results show that the TSA-based controller has better voltage support and control signal performance. The TSA-based controller also improves the settling of oscillation damping. The proposed method shows robustness of the damping control by presenting different contingency scenarios.","PeriodicalId":296428,"journal":{"name":"2017 North American Power Symposium (NAPS)","volume":"35 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124225007","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}

Based on the Center of Inertia (COI) concept, this paper presents a practical study on the inertia distribution estimation, which can be used to both planning in long time scale and operation in short time scale, to meet with increasing renewable integration level in the future power system. Two indices are created to calculate the inertia distribution over the grid. Specifically, it is found that the proposed indices are highly related to the grid structure, and also they are affected by different parameters such as inertia constant, line parameters, terminal voltage set point of synchronous machines and models of exciters and governors. With these characteristics, the proposed indices have the potential to be applied on problems such as the placement of phasor measurement units or energy storage systems and generators coherency detection. Simulation results in a radial system, a meshed system and the IEEE 39-bus test system verify the characteristic of the proposed indices and show their potential applications in modern power systems.","PeriodicalId":296428,"journal":{"name":"2017 North American Power Symposium (NAPS)","volume":"15 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121257621","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}
