The government of Japan assumes that a large portion of renewable energy in the near future will be provided by photovoltaic generation systems installed at end consumers. Thus, smart grids in Japan will be established mainly at the distribution and the end-consumer level of power systems. Considering this situation, the Smart Grid Working Group, created inside the Cooperative Study Group on Applications of Power Electronic Simulations of IEEJ (Institute of ElectricalEngineers of Japan), is currently discussing and developing standard simulation models for components of the distributionand the end-consumer-level power systems. These components include distribution substations, distribution lines, voltage regulation equipment, pole-mounted transformers, photovoltaic panels, power conditioning systems, Li-ion batteries, and small and micro wind power generation systems. The purpose of developing the standard models is to use in transient simulations related to smart grids. This paper describes the present state and the future plan of the development of the standard models.

-The study presented in this paper is a first step of an EMC (Electromagnetic Compatibility) analysis of the behaviour of a railway power substation at high frequency. Before on site intensive experimentation, the approach is performed with a reduced scale model. The mock-up of the substation is powered by a 220 V three-phase voltage supplied by a 15 kVA power transformer, a rectifier and loads. The study consists in designing an equivalent electrical circuit of power transformer in high frequency, available over a large panel of loads. The model of power transformer was deduced from measurements in frequency domain within the range 40 Hz to 30 MHz.

In this paper a straightforward model is proposed for transient analysis of transformers. The model is capable of representing the impedance or admittance characteristics of the transformer measured from the terminals under different terminal connections up to approximately 200 kHz. The model is simple, so that the simulation with this model is easy and fast. It is feasible to use the model as a two port element by network analysing. To estimation of model parameters genetic algorithm is used. Outset of all, the required measurements are carried out on the 2500 KVA, 6300/420 V transformer. Thereafter, the model parameters are estimated using genetic algorithm toolbox in MATLAB. The comparison between calculated and measured quantities confirms that the accuracy of the proposed method in the middle transient frequency domain is satisfactory. Finally, one of important application of proposed model in transformers fault detection is discussed.
