Distributed generation for the provision of operating reserves

Among the ancillary services, the operating reserves are important researching aspects, which deal with supplying way and selling-buying prices. Currently, distributed generation (DG) rises as a new participant in providing ancillary services, therefore, it is of main importance in operating reserves subject. This work shows some advantages and technical drawbacks by using DG when operating reserves are supplied. Different sceneries were computed where the electric generation was performed in a centralized and non-centralized way respectively. A methodology for identifying the maximum DG, which can be allocated, is proposed; this maximum level can be assessed without carrying out a negative impact in the network. The operative reserves price provide by generation distribution is analyzed. Diverse DG technologies, which present better performance in supplying such reserves, are also presented.
