Additional energy saving can be obtained by considering wind power with more proper approach in system scheduling and dispatching. Considering wind power output in mid-long term planning coordinated with short-term scheduling can further reduce the fuel consumption by optimizing resource distribution. Wind speed and wind power cannot be predicted more than one week earlier according to the present technology, which means the mid-long term unit commitment considering wind power output much differs from the traditional one and the short-term unit commitment considering wind power. A dynamic clustering idea is presented which determines the commitment plan of some part of conventional units in the mid-long term planning and determines that of the rest units in the short-term planning. It is based on the advantages of the two scheduling periods that mid-long term planning is more conducive to optimize resource distribution and reduce the total start-up costs, whereas short term planning contribute to reduce the load rate and reserve requirement due to the significant reduction in the uncertainty of wind power output. A two-stage monthly unit commitment model considering short term scheduling for systems with wind power integration is developed to minimize the expected monthly total costs. The effective decision variables contain the group of each conventional unit belongs to and the commitment variables of the units belonging to the monthly optimizing group. Simulation results on the revised IEEE-118 bus system verified the proposed method.","PeriodicalId":142885,"journal":{"name":"2018 China International Conference on Electricity Distribution (CICED)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2018-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114139206","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}

Although electrical vehicle (EV) dose produce less carbon emissions and the less fossil fuel are consumed compared with traditional vehicles, the electricity should be supplied to EV battery charging where excess emissions would be produced from power generation. In this work, we try to optimize the power dispatch for the extra electronic vehicle loading exemplified by the Ireland's electricity market in 2020 with a commercial PLEXOS software. We have investigated the effects of the EV load on the SEM (Single Electricity Market) with the four different scenarios including peak, off-peak, stochastic, and EPRI, respectively. The simulative model was used to optimize the dispatch of a generation and supply energy for a specified demand load. It was confirmed the EV charging at the peak time presented the highest increasing in the systematic marginal price, generation costs and total C02 emissions. The off-peak charging is more beneficial than other charging modes that would contribute 1.54% renewable energy penetration and supply to the 200% emissions reduction target. The present work may provide a new idea and technological approach for the sectional dispatch of the power grid and optimizing EV load in the future.","PeriodicalId":142885,"journal":{"name":"2018 China International Conference on Electricity Distribution (CICED)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2018-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114238161","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 order to summarize the difference, this paper introduces a MIMO-based analysis tool for modelling power systems integrated by conventional or power-electronic interfaced generators. The scalable tool is used to test modelling accuracy of individual generators using dynamic simulation. For small-signal stability analysis, the tool does linearization based on MIMO models, and then couple all generators/loads though the passive network, with the network transient included. During transient stability analysis, VSG's ability to emulate SG's dynamic responses depends on whether the converter has a strong overloading limit, and the current control loop is tuned fast. In practice this could be hard to realize, considering that the converter's current limit is slightly higher than 1.0, and thus the current controller tends to be easily saturated during voltage sags, and the VSG could enter constant-power mode. During small disturbances, VSG could have a low-frequency inertia response similar to SG, yet it can introduce new oscillation modes, depending on the control parameter configuration. Due to lack of stator-flux transient modelling, the high-frequency oscillation of VSG is evidently deviated from that of SG.","PeriodicalId":142885,"journal":{"name":"2018 China International Conference on Electricity Distribution (CICED)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2018-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115249247","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 trip fault of the power transmission line caused by the typhoon has occurred frequently, so the risk assessment of the transmission line under typhoon disaster is increasingly important. This paper summarizes some typical cases of typhoon around the world, and concludes the main reasons for the trip of transmission lines, including windage yaw, floater, tower damage, broken line, lightning stroke and so on. In view of the reasons of the trip, the Monte Carlo method, fuzzy mathematical model, machine learning algorithm, probability model, regulation method and improved electrical geometry model are introduced. The model and so on are applied to the risk assessment method and model of transmission line trip, and the preventive measures for transmission line failure under typhoon disaster are put forward. By summarizing the relevant literature on the risk assessment of power system at home and abroad, the existing literature on the risk assessment of power system in bad weather is more, but the research on the risk assessment of transmission line trip under typhoon disaster is less. Finally, this paper looks forward the development prospect of the risk assessment of transmission line trip under typhoon disaster.","PeriodicalId":142885,"journal":{"name":"2018 China International Conference on Electricity Distribution (CICED)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2018-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121002184","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}

It is particularly important to evaluate the distribution network power supply reliability after the distributed energy access. In this paper, a pseudo-sequential Monte Carlo simulation method is proposed to evaluate the reliability index of distribution network with fans, photovoltaic cells and batteries. The system state is sampled by non-sequential Monte Carlo method. Only the sequential Monte Carlo simulation of the fault process can quickly and accurately obtain the reliability index of the distribution network, which is suitable for large-scale networks after a large number of distributed energy access in the future. In the process of sequential simulation, micro-grid operation, distributed energy use strategy and optimal load shedding strategy are considered simultaneously.
