Solar water heating (SWH) systems are well known and effective structures that transfer solar energy into thermal energy with hot water as the storage. The efficiency of an SWH system is mainly based on well-designed solar collectors and proper operation mechanisms. Although the most existing literature has focused on the efficiency enhancement of solar collectors, limited studies are devoted to improve the operating mechanism. As such, this paper studies the control mechanisms of the SWH system with a purpose so as to help the building manager to achieve targeted energy management goals. In particular, three control approaches are presented for improving the operational efficiency of the SWH system by controlling auxiliary heaters, such as heat pumps, electric heaters, and circulation pumps. The proposed approaches are developed based on different requirements of information such as the hot water demand, weather, and electricity price. Moreover, three various energy management objectives are studied with considering different scenarios in terms of real weather pattern and hot water demand of a commercial building. The results validate that the proposed approaches can improve the operation of the SWH system according to various operation objectives.

We model the dynamics of solar thermal plants—the first model covering all processes between market demand through power output at millisecond resolution—for the purpose of control design. Our model integrates solar reflectors, power tower, salt tank, boiler, turbine, generator, piping, and pumps along with the flows of energy and information between them. We show how our detailed model permits control designs that can potentially enhance the life of the power tower, and thereby aid in reducing ...

This paper proposes a novel electric vehicle (EV) classification scheme for a photovoltaic (PV)-powered EV charging station (CS) that reduces the effect of intermittency of electricity supply and the cost of energy trading of the CS. Since not all EV drivers would like to be environmentally friendly, all vehicles in the CS are divided into three categories: 1) premium; 2) conservative; and 3) green, according to their charging behavior. Premium and conservative EVs are considered interested only...

For a new district in the Dutch city Meppel, a hybrid energy concept is developed based on bio-gas co-generation. The generated electricity is used to power domestic heat pumps which supply thermal energy for domestic hot water and space heating demand of households. In this paper, we investigate direct control of the heat pumps by the utility and how the large-scale optimization problem that is created can be reduced significantly. Two different linear programming control methods (global MILP a...

Abstract Augmentation of solar radiation absorbed on a flat plate solar thermal collector by a flat plate bottom reflector was numerically determined when there was a gap between the collector and reflector. The inclination of both the collector and reflector was assumed to be adjustable according to the season. A mirror-symmetric plane of the collector to the reflector was introduced, and a graphical model was proposed to calculate the amount of solar radiation reflected by the reflector and th...

Time-based demand response (DR) enables industrial consumers to transfer their power consumption by following daily price curve. However, general time-based DR is basically a passive tariff. Utilities usually create general pricing tariff to the whole industrial consumers at the same voltage connection level. Under this situation, consumption transformation of all possible industries occurs together. It may reduce the effect of load characteristics improvement. This paper introduces a new pricin...

Abstract This paper formulates a risk-based robust decision making framework for a Smart Building (SB) energy management system under demand and supply uncertainty. The last aim of the resulting multi-objective mixed integer linear programming is to minimize the total day-ahead cost of the system, in which the objective functions are the total cost of heat and power co-generation, and the total emissions cost. In this way, the first trade-off is made between economy and environmental impacts, wh...
