In order to accurately evaluate the issue of harmonic responsibility generated by distributed generations and individual customers, this paper proposes a method of harmonic responsibility division based on ideal load current. There are two indices named ideal load current and the non-ideal load current are defined according to the ideal load characteristics. Depending on the harmonic voltage propagation characteristics of distributed generation and non-linear load, the ideal load parameters of microgrid are calculated by analyzing multiple harmonic source equivalent networks of microgrid from the perspective of individual customers, and the harmonic current generated by background harmonic voltage is decoupled from the ideal load current under the condition of deterioration of the voltage waveform, and the load harmonic current is decoupled from the non-ideal load current to realize the harmonic responsibility division of the microgrid. The proposed method does not need to calculate the network structure and system impedance information. Several cases of simulation analysis prove the validity and rationality of this method.","PeriodicalId":260947,"journal":{"name":"2018 International Conference on Power System Technology (POWERCON)","volume":"15 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125291491","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 current measuring technique allows for three phase current measurements from the outside of a three phase cable. It will be evident from the paper that the existing voltage and current measurement transformers suffer inherent limitations when targeting low cost power system analysis and asset management and new sensing techniques are required. The new current and voltage measuring technique will be presented in this paper along with measuring cases from the field to proof the effectiveness of this new sensor. The sensor can operate as a mini localized SCADA system by performing a wide variety of power system analysis both in long-and short term, but the sensor can also operate as a traditional measuring device and transmit the low level data to the SCADA system. It will be evident from the paper that this localized data processing method in combination with the disruptive current measuring technique can pave the way for the distribution grid to become just as smart as the transmission part of the grid is already. The much better cost/performance ration suddenly makes ‘smart grid’ possible all over the secondary substations.","PeriodicalId":260947,"journal":{"name":"2018 International Conference on Power System Technology (POWERCON)","volume":"24 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125323561","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 MATLAB/Simulink, this paper researches on the modeling and simulating of photovoltaic power generation system and battery energy storage and their equivalent model. First, a detailed model of the photovoltaic system is built. Boost circuit and MPPT control are selected on the DC side of photovoltaic power generation system. The double closed loop control method of current internal loop and external voltage loop is used for grid inverter control. The model is improved considering the capability of LVRT (low voltage ride through). Based on the above precise models, the model is equaled. The equivalent transfer function is calculated by the grid connected control loop, so the model is simplified. The battery energy storage module establishes a general mathematical model based on the charging and discharging principle. Charge and discharge are controlled through the DC/DC converter. And it is connected to the power grid after inverting and filtering. The common PQ control are selected in the inverter control mode. According to the same principle, the energy storage model is equaled. Finally, based on the traditional load model, the above load model is added to set up a new generalized integrated load model. And the actual model is replaced to build up an equivalent model. The equivalent model is compared with the actual model to verify the equivalent description ability.","PeriodicalId":260947,"journal":{"name":"2018 International Conference on Power System Technology (POWERCON)","volume":"26 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115198921","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}

A novel dynamic equivalent method is proposed for large-scale power systems electromagnetic transient modeling, which could reflect the characteristics of power alternation via electromagnetic loop and local accommodation among generators and loads in the equivalent network. The key method is to determine an equivalent bus for each node located in the equivalent section firstly, calculate the equivalent bus voltage(magnitude and phase) as well as the impedance of the equivalent tie branch follow the principle of unchanged of power flow and total current of the boundary transmission sections based on the initial operation point of the original power grids, then compute the effective sending power ability of equivalent coherent generators, and the effective receiving power ability for each equivalent bus.

Hence, network pricing should take network security into consideration. In the original long-run incremental cost(LRIC) pricing method, security factor is defined to charge for network security. It assumes that security factor is constant before and after the nodal injection. This paper proposes an improved LRIC pricing method, considering the fact that security factor of each component will be changed with nodal injections. This paper analyzes the factors that affect the security factor and illustrates the improved LRIC method with dynamic security factor. To demonstrate the difference between the improved LRIC pricing method and the original LRIC pricing method, simulation studies are conducted on a three-nodes system and the IEEE 14-nodes system, respectively; and the results show that the improved LRIC method can more accurately reflect the impact on network costs from users and ensure more reasonable allocation of network costs.","PeriodicalId":260947,"journal":{"name":"2018 International Conference on Power System Technology (POWERCON)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122297647","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}
