With the shortage of traditional fossil energy and environment problem aggravating, renewable energy and CHP or CCHP, which is considered as a method for the efficient use of energy, have received a great deal of attention. How to improve the utilization rate of renewable energy and achieve maximum economic revenue now seems very important. In this paper, an optimization model of a combined heat and...
Combined heat and power system (CHP) with renewable energy generation, which operates with high efficiency and low costs, is an important form of microgrid. This paper deals with the problem of economic operation of cogeneration system including wind energy, PV, heat recovery boiler and battery. On the basis of predicting the next 24-hours' wind energy and PV power, power and heat demand, a nonlinear...
This paper discusses investment strategies in a microgrid system consisting of cogeneration system and renewable power generation under uncertainty in the natural gas price. Although incentives for introducing distributed energy system increase these days, volatile natural gas prices make its investment in gas fuel distributed generation systems risky. Therefore, it is important to evaluate the risk...
Renewable and nonconventional distributed energy resources (DERs), such as, wind, solar PV, microturbines, fuel cells, diesel generators etc. are gradually becoming more popular as energy efficient and low-emission energy sources. Recent deregulation initiatives in power and energy industry are currently influencing company decisions regarding the construction of new generation plants and transmission...
