With the rapid development of electricity production, SO2 from coal-fired power stations causes severe air pollution problem. In 1997, the SO2 emitted from thermal power plants reached 7.,0 Mt, accounting for about 33% of the national emissions. At present and in the future, th...

In this paper, a photovoltaic(PV) generation system based on front-stage differential power processors(DPP) and BACK-stage centralized wide voltage-gain converter is proposed. The resonant switched capacitor(ReSC) converter, which features high power density and high efficiency, is employed as the d...

The reliability level of a power generation system is an important problem which is concerned by both electricity producers and electricity consumers. Why? It is known that the high reliability level may result in additional utility cost, and the low reliability level may result in additional consum...

Reliable sampled value (SV) synchronization is used to ensure the reliability of protective relaying in a smart substation based on IEC 61850. In this paper, an SV synchronization method based on SV propagation delay measurement and compensation is proposed. The method does not depend on an external...

The distribution substation planning is faced with numerous uncertainties so that the planning result can only be a "rough outline," and the problem of determining the planning period arises. On the basis of the assessment of uncertainties in distribution planning, a specific approach to determine t...
