Accurate calculation of power systems ancillary services

Power System Ancillary services are those functions performed by the equipment and people that generate, control, and transmit electricity in support of the basic services of generating capacity, energy supply, and power delivery.;Although substantial progress has been made in identifying and defining the key services, much remains to be done to specify methods to measure the production, delivery, and consumption of these services Developing metrics, determining costs, and setting pricing rules are difficult and important because most of these ancillary services are produced by the same pieces of equipment that produce the basic electricity commodity.;Different analysis tools have been implemented by other researchers, most of them based on linearizations of the system.;With a large number of transactions running simultaneously in a heavily loaded system large errors and miss-allocations are occasioned and consequently the lost of fairness whereby they were envisioned.;This research presents a new methodology to calculate Energy Transaction Allocation factors (ETA factors), using a path integration method.;The factors give a highly accurate allocation of any non-linear system quantity to transactions placed on the transmission system. The thesis also extends the ETA factors calculation procedure to restructure a new economic dispatch scheme where multiple sets of generators are economically dispatched to meet their corresponding load and their share of the losses.
