Smart distribution networks (SDNs) plays a significant role in future power networks. Accordingly, the optimal scheduling of such networks, which include planning of consumers and production sections, inconsiderably concerned in recent research studies. In this paper, the optimal planning of energy and reserve of SDNs has been studied. Technical constraints of distribution network and power gen...

Abstract This work addresses the scheduling of continuous single stage multiproduct plants with parallel units and shared storage tanks. Processing tasks are energy intensive and we consider timedependent electricity pricing and availability together with multiple intermediate due dates, handled as hard constraints. A new discrete-time aggregate formulation is proposed to rapidly plan the produ...

The study of mid- and long-term output characteristics photovoltaic power plants is great significance for the prediction generation optimal scheduling multi-energy complementary. This paper uses historical operation data a plant in Shandong Province to important factors affecting station. Furthermore, model conducted which more suitable engineering practice, considering temperature, dip angle ...

Transformers in power plants act as intermediaries between the power plant and the power grid, which are affected by electrical stresses such as switching, thermal stresses such as overload and arc, and chemical reactions in the dielectric oil. Acid and moisture components cause deterioration of transformer oil and paper insulation. Condition assessment of transformers is a method to predict an...

As power systems increasingly rely on gas-fired power plants (GFPP), and as thermal cycling requirements increase due to larger penetrations of intermittent generation, the long-term service agreements (LTSAs) that define the conditions and costs for GFPP maintenance are exerting more economic influence over a power system’s short-term operations. In a previous paper, the authors proposed a uni...

Turbochargers are used to increase engine manifold air pressure. Control of intake manifold pressure is crucial issue which is done through the speed control of turbocharger, but since it is difficult to directly control the speed of the turbocharger, it is done indirectly through a gate that called the waste gate, which is located in the engine outlet and turbocharger’s turbine inlet. One of t...

This paper aims at estimating the efficiency of hydroelectric power plants (renewable energy resources) and thermal power plant (non-renewable energy resources) in Iranian provinces. Data Envelopment Analysis (DEA) approaches is applied to estimate the efficiency. The network is modeled as a linear system with multiple inputs and one output. Fuel cost, labor force, operation cost are used as in...
