This paper presents a hierarchical control strategy for heat and electric power control of a building integrating hybrid renewable power sources including photovoltaic, fuel cell and battery energy storage with Plug-in Electric Vehicles (PEV) in smart distribution systems. Because of the controllability of fuel cell power, this power sources plays the main role for providing heat and electric p...

The renewable energy sources and plug-in electric vehicles (PEVs) are becoming very popular because of the combination of high fuel costs and concerns about emission issues. This paper presents modelling and control of a Building Integrated Fuel Cell and Plug-in Electric Vehicles (BIFC-PEV) in smart distribution systems. In BIFC-PEV system, conventional building elements could be replaced by sp...

The increment integration of renewable distributed energies means the desired operation of the electric power system will significantly depend on the performance of primary energy. In this order, an integrated approach for mutual interaction between the electricity and natural gas systems has been considered for the purpose of ensuring optimal energy exchanging between the electric power system...

In this paper we analyze the response of the electric power grid to a hypothetical nuclear attack inside a major city in the US. We assume that the protective devices of the power system located within a given distance of the attack will be affected by the resulting radiation and hence will not work. A probabilistic examination of the resulting power surges indicates that, if left unchecked, th...

Introduction Fast, efficient batch melting using the modern induction furnace can improve operating flexibility and production yield, as well as reduce the cost of environmental protection. The compelling advantages of induction batch melting have encouraged foundries to change the way they handle their melting operations. Among the chief advantages is cost. The operational cost of a typical in...

As a result of the Great East Japan Earthquake in March 2011, electric power supply in Japan faced a critical situation; in particular, factories that consume a large amount of electric power were seriously affected. Meanwhile, in China and other emerging countries, where the economic growth rate is high and automation of manufacturing factories is progressing, further energy saving is a key is...

Parameters estimation of dynamic model of synchronous generators is an essential prerequisite for viable and reliable power system operation and offline studies. Advent of phasor measurement units (PMU) and its growing applications in power systems have led to an evolution in the electric power network wide-area monitoring, protection, and control. Alongside, these devices have revealed unprece...
