The reliance on energy is continuously growing as our consumption increases each year. This reflect that our natural resource capacity is hitting rock bottom sooner and sooner. Therefore, it is inevitable to explore a secondary source or by optimising current technology for the future generation. In this final year project (FYP), a closely study into the optimisation of widely used combined cooling heating and power (CCHP) system is carried out. Base on the study, an optimal strategy on operational dispatch with consideration of environment factor, the gas emission, of CCHP based system microgrid is proposed. The project proposed is a multi-objective function, 1) to minimise the operational cost; 2) is to reduce emission gas from generating unit. Total of 2 strategies is discussed and compare, following the thermal load and coordinated distribution. The strategies are optimised through MATLAB YALMIP solver, providing concentration on efficiency modelling and high-level algorithms. The simulated result reflects that the proposed strategy could provide benefit in reducing operating cost and the pollutant gas released from the generating units. This observation gives added confirmation that further improvement on current technology such as CCHP system can help to save energy crisis.
