In order to control the power flow from DC bus of such generating units to AC grids, grid-connected inverters are essential. This paper proposes an optimization-based control method for single-phase grid-connected inverters which could be considered as a mixture of Model Predictive Control (MPC) and Direct Power Control (DPC). The proposed method minimizes switching frequency and, simultaneously, takes into account power quality constraints such as standard output current harmonics and Total Harmonic Distortion (THD). Due to long computational time required for running optimization problem, solutions for a set of outputs are computed off-line and stored in a look-up table. An open-loop control method based on the look-up table is proposed. Furthermore, in order to provide small signal regulation and disturbance compensation, an on-line algorithm is implemented. Simulation results assure that, the method works accurately in an ideal environment and dramatically lower switching frequencies are achieved. In addition, the closed-loop method not only provides continuous control on output power, but also compensates possible disturbances.","PeriodicalId":445295,"journal":{"name":"2013 13th International Conference on Environment and Electrical Engineering (EEEIC)","volume":"3 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114545738","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 this type of interrupters, energy dissipated by the arc, during high current phase, is stored as potential energy in the gas. At current zero, gas flow created by the stored energy, sweeps the arc out of the gap between the arc contacts. The cool gas from the compression volume (puffer volume) is introduced in the thermal volume as well as between the arc contact gap for recovery of the gap dielectric strength. This will help to withstand against the applied transient recovery voltage (TRV) and complete the interruption successfully. Arc assist interrupter has two gas chambers, one which generates high pressure by using heat of the arc and other chamber generates high pressure by mechanical compression. Magnitude of short circuit current will decide the pressure developed inside the thermal chamber. For lower current duties, pressure developed by the arc during interruption is less so it is critical to clear the lower current duties for arc assist circuit breakers. This paper deals with variation of clipping pressure to generate the adequate pressure required for arc quenching for lower current duties. In this we have used 3 variations of clipping pressures as 5bar, 7bar and 10bar and results were analyzed. This paper discusses the effect of clipping pressure variation on pressure generation in compression chamber, Thermal Chamber and also density and temperature variation between contacts at current zero during interruption of arc.","PeriodicalId":445295,"journal":{"name":"2013 13th International Conference on Environment and Electrical Engineering (EEEIC)","volume":"32 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114547786","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 addition, the DSM promotes the integration of the new renewable sources power generation systems in the traditional electrical grid, improving the balance between local supply and energy demand. This paper proposes a novel DSM technique based on a non-cooperative game framework, to reduce the Peak to Average Ratio (PAR) of the power system, minimizing daily electricity payment of each consumer in the geographical area. Each consumer is considered like a player in an energy game and he/she is encouraged to re-schedule the energy consumption, applying an MPSO algorithm to shift in time those loads occurring during peak consumption periods. The dynamic pricing policy applied by the energy providers, leads each player to adopt the best strategy among its Pareto scheduling solutions, to minimize the energy peak in the overall load demand of a geographical area. Simulation results confirm the effectiveness of this distributed game theoretical approach to the DSM problem. An appreciable PAR reduction is achieved at the price of a low information exchange between the energy provider and each consumer, keeping the user privacy safe and minimizing the overhead of signaling information over the network.","PeriodicalId":445295,"journal":{"name":"2013 13th International Conference on Environment and Electrical Engineering (EEEIC)","volume":"24 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122159172","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}

Islanding detection methods are categorized into three groups, i.e., communication based methods, active, and passive methods. Communication based methods are established upon communication between utilities and DGs and have the inconvenience of being expensive and are limited in use. Active methods perturb the system with a disturbance and the system response to the disturbance is analyzed. Although, these methods have small Non Detection Zone, (NDZ) they degrade the power quality. Passive methods monitor one of the grid variables. Their implementation is easy but their NDZ is large. This paper proposes a hybrid islanding detection method which uses voltage unbalance (VU) and high-frequency (HF) impedance. The proposed method merges the advantages of both active and passive techniques. In addition, since the active method used in this paper does not change any of the system variables as a disturbance, it will not lead to any instability. To test the proposed method, UL1741 test system is simulated in PSCAD/EMTDC and the simulation results indicate that the proposed method can identify islanding in 32ms (2 cycles) and it does not mal-operate while other system events like faults and switchings.","PeriodicalId":445295,"journal":{"name":"2013 13th International Conference on Environment and Electrical Engineering (EEEIC)","volume":"69 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121445413","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 investigation is based on dynamics time domain simulations by DigSilent software and aims to define the main functions for the power management system (PMS) that will govern the operation of the power plant. In this paper, DigSilent Simulation Language (DSL) is used for simulation of Turbine-Governor and excitation system. Also DigSilent Program Language (DPL) is used to simulate action of PMS when it is required. Also, different dynamic contingencies related to Damavand power plant such as Trip of grid connection, Trip of One GT, Trip of load, Trip of Two GTs, Trip of Grid connection (According to governor logic, Automatic change mode acts, Solving frequency deviation by PMS) are considered. In each scenario, power plant stability is investigated and where required, PMS functions (such as load shedding and sending appropriate set points) are applied.","PeriodicalId":445295,"journal":{"name":"2013 13th International Conference on Environment and Electrical Engineering (EEEIC)","volume":"80 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127560756","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}
