Distributed generation for the provision of operating reserves

Abstract

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.

Active Distribution Grids Offering Ancillary Services in Islanded and Grid-Connected Mode

“…[15] focuses also on the optimal scheduling of an active DN providing frequency regulation, load leveling and ramping services. Offering ancillary services by various DER technologies is explored in [8], while [9], [10] analyze the economic feasibility and the potential amount of reserve provision by distributed generation. However, they do not consider BESSs or include network constraints.…”

Active power reserve for frequency control provided by distributed generators in distribution networks

“…In [10], authors present a study of reactive power support services, frequency control and black-strart provided by DGs. The viability, strategy of control, effectiveness and cost-benefit analysis of various ancillary services provided by DGs are presented in [11]; and technical advantages when DGs are used for reserves of active and reactive power are presented in [12].…”
