Technical and Tariff Scenarios Effect on Microturbine Trigenerative Applications

Abstract

The paper considers the use of gas fired Micro Turbine Generators (MTG) for tri-generation (combined production of electricity, heating and cooling) applications in tertiary buildings. The importance of the adopted MTG technology is investigated, showing that the high electrical efficiency levels achievable by future advanced ceramic MTGs would improve dramatically the economic competitiveness of the application, as well as the primary energy savings and environmental benefits. Calculations are performed by the simulation code TRIGEN, capable of optimizing the plant operating mode in each time step and integrating the results over the entire year. The requirement of a “target” energy saving index on the optimization procedure is also addressed.

System Modeling and Multi-objective Optimization of Micro-grid Using Bender's Decomposition Algorithm

“…The constants values of DGs and MT are used in the model are shown in Table 2. [11], [12] and emission constants are tabulated in Table 3 [13]. Comparison of results of proposed benders algorithm for defined MG operation problem is tabulated in Table IV.…”

“…All the formulas can be mathematically written as follows: ) (16) subject to: P i is vector of generated powers, CF(P i ) is calculated cost function according to equation (11),g i is equality constraint according to the equation (14) and finally h i inequality constraint according to the equation (15).…”

Trigeneration: A comprehensive review based on prime movers

“…A sensitivity analysis was conducted by [80,81]. Campanari et al [80] and Campanari and Macchi [81] used the same model that consisted of single effect and electrical chillers.…”

A model for micro-trigeneration systems based on linear optimization and the Italian tariff policy

“…Such a choice may often be non-optimal; therefore many works started to be devoted to the optimization of the operating policy. In general, two different viewpoints are adopted: some studies analyse the system and its components in great detail [11,12,13], while the optimization technique in itself is not very sophisticated; in other papers the main focus is on the mathematics of optimization [14,15,16,17,18] with a minor description of the system from an engineering point of view. Recently, a few research groups proposed extended analyses including environmental and legal constraints, together with the use of storage systems [19,20,21,22,23,24,25 …”
