摘要:CHP-based micro-grid is stipulated to serve its customers with both electrical as well as thermal demand simultaneously, but from operational point of view, it is to opt either tracking of electrical demand profile or thermal. At the planning stage, owner of the micro-grid could evaluate which mode would be most economically beneficial to his system for investment. Maximization of net present value (NPV) of the 6-bus meshed and 14-bus radial micro-grid have been used in the present paper as an important decision making tool, along with internal rate of return (IRR) and payback period (PP) as supporting tools. As per the above tool, higher the benefits accrued from the system at lower investment, better is the choice of the mode of operation. As both higher benefits and lower investment are related with proper locations, capacity-sizes and types of DERs, Loss sensitivity index (LSI) method has been used, here, to take care of optimal locations, whereas optimal sizes and its separation into micro-turbines and diesel generators have been done using particle swarm optimization (PSO) technique with an object to maximization of NPV under certain power quality and reliability (PQR) constraints.
