“…However, the number of studies in literature based on real data from trigeneration plants connected to a DHC is very scant. Thus it is clear that the current literature lacks empirical or operational data to validate thermodynamic models of integrated systems with multiple components [9,13]. Also there is no information on the actual energy efficiency of trigeneration plants working at low partial load.…”

“…Many studies have been carried out such as Hajabdollahi et al [10], Chicco and Mancarella [11] and Stojiljkovic et al [12], just to mention a few, to optimize the operation and/or design of trigeneration plants using partial load characteristics and different optimization approaches and objectives [13] including in some cases thermoeconomic and exergy analysis [14] or environmental information obtained through life cycle analysis techniques incorporated into the optimization model [15]. In some cases the main interest is focused in the design of new trigeneration systems for DHC networks for different cases such as big urban areas [16], for small scale applications with the integration of renewable energy sources [17] or to study the combined effect of optimized energy supply systems and reduction of home energy demands [18].…”

Optimal Cooling Load Sharing Strategies for Different Types of Absorption Chillers in Trigeneration Plants

2016

Trigeneration plants can use different types of chillers in the same plant, typically single effect and double effect absorption chillers, vapour compression chillers and also cooling storage systems. The highly variable cooling demand of the buildings connected to a district heating and cooling (DHC) network has to be distributed among these chillers to achieve lower operating costs and higher energy efficiencies. This problem is difficult to solve due to the different partial load behaviour of each chiller and the different chiller combinations that can cover a certain cooling demand using an appropriate sizing of the cooling storage. The objective of this paper is to optimize the daily plant operation of an existing trigeneration plant based on cogeneration engines and to study the optimal cooling load sharing between different types of absorption chillers using a mixed integer linear programming (MILP) model. Real data from a trigeneration plant connected to a DHC close to Barcelona (Spain) is used for the development of this model. The cooling load distribution among the different units is heavily influenced by the price of the electricity sold to the grid which rules the duration of the operation time of the engines. The main parameter to compare load distribution configurations is the primary energy saving indicator. Cooling load distribution among the different chillers changes also with the load of the whole plant because the chiller performance changes with load.

“…Despite the aforementioned works, it is important to note that the type, size and configuration of technologies for an energy system cannot be decided without consideration of its operating strategy. Regardless of the application and technologies employed, the operation strategy is the critical factor governing the overall layout and performance of any energy system (Cho et al 2014;Jradi and Riffat 2014). With a suitable operating strategy, the energy system is able to reduce its overall fuel consumption and subsequently its operational costs.…”

“…Several works have been reported in literature which study different operation strategies for an energy system (Cho et al 2014;Jradi and Riffat 2014;Liu et al 2014). According to Kavvadias et al (2010), the two commonly investigated operation strategies in industry are:…”

An energy system is a crucial component in fulfilling the energy requirements of a given industrial process. If not designed appropriately, energy systems may not be able to perform designated operations in an optimised manner. Mathematical optimisation approaches have had a long history in addressing the synthesis of energy systems. Mathematical optimisation approaches are part of a larger domain known as process systems engineering (PSE). The main objective of this review is to provide a state-of-the-art overview of the mathematical optimisation approaches developed, particularly those developed for synthesis of energy systems, including the handling of uncertainty and the optimisation of multiple objectives. Subsequently, the synthesis of energy systems is further discussed on specific areas such as reliability, operability, flexibility and retrofit and eco-industrial parks. Following this, an overall analysis of the contributions in these areas is provided. Finally, future research directions are identified at the end of this review.

Abstract.Research on distributed power generation as an alternative method to the conventional power generation system continue to be developed to improve its commercialization capabilities. The cogeneration system and trigeneration system are technological improved alternatives in distributed generation where they offer enhancement and reliability in term of efficiency, emission performances and economic benefits. However, it is more feasible to implement the trigeneration system for most commercial and domestic distributed generations as the cooling demand is deliberately high compared to heating demand especially in hot and humid climate locations. Moreover, micro gas turbine is observed to be a beneficial prime mover in cogeneration and trigeneration system based on several criteria such as ability on acquiring high heat to power ratio characteristic as well as lower greenhouse gas emission. On the other hand, the role photovoltaic in building integrated system provides opportunities for renewable energy system engagement in trigeneration based distributed generation systems. This paper emphasize on summarizing the research work perform on cogeneration system or trigeneration system in hybrid mode with photovoltaic. There are also preceding sections on overviewing the state of art of cogeneration system and the trigeneration system as well as photovoltaic technologies in power generation.
