Distributed energy resource capacity adequacy assessment for PQR enhancement of CHP micro-grid

Generation disruption is associated with poor quality of power as it causes both frequency and voltage reductions and at its severity, hampers reliability of supply to the customers. Improving power quality and reliability (PQR) may become the key benefit of micro-grid if its generation adequacy is properly addressed at the planning stage. Again, higher reliability level requires system reinforcements, which could, in turn, result in higher customer rates. A best possible trade-off is required at the planning stage between cost and reliability. Present paper uses LOLP, LOEP and FAD probabilistic methods for efficient assessment of reliability of CHP-based DERs capacity of a 6-bus meshed micro-grid in the context of tracking of electric demand profiles. Worth of reserve capacity and demand for reserve with these fast-start DERs are evaluated from capacity outage probability distribution and demand curve.
