The demand for electrical energy grows exponentially over time and most of electrical power generation is produced from fossil fuel. The increase in fossil fuel utilization results in excessive greenhouse gas emission to environment which paves way for global warming and natural disasters. The United Nations Framework Convention on Climate Change (UNFCCC) guides the global community on utilisation of emission-free renewable energy. Stochastic nature of wind renewable energy is not promising in emission reduction while operating in parallel with central power generation. As an alternative this report is developed to integrate the uncontrolled wind / renewable power with distributed generation. Several previous research works qualify the feasibility on integration of renewable and fossil fuel power generation at a remote network / distributed generation (DG). However in practice distributed generations exist with cogeneration/combine heat & power generation (CHP) to utilize the heat while producing electricity to attain maximum fuel utilization. This maximum fuel utilization increases system efficiency and reduces the emission. For further emission reduction from CHP, this report suggests a new concept. The new concept proposes integration of CHP with renewable power generation. As part of this report, a scenario is evaluated where wind power integration with a reciprocating engine CHP is carried out. Considerable emission reduction is obtained from the integration model. For evaluation of this new integration concept with the other type of CHPs and other than wind renewable, an algorithm is presented as part of this report.
