TLDR
In this article, the authors discuss the potential of distributed generation (DG) to provide some of these services, such as voltage sag compensation and harmonic filtering, and the implications on the design of the power converter interface are discussed.Abstract:
The growing concerns regarding electric power quality and availability have led to the installation of more and more distributed generation. In parallel and in the context of an accelerating trend towards deregulation of the electric industry, the unbundling of services, many grouped under ancillary services, should create a market for some of these services. This paper discusses the potential of distributed generation (DG) to provide some of these services. In particular, DG can serve locally as the equivalent of a spinning reserve and voltage support of the AC bus. The main types of distributed generation with emphasis on the power electronic interface and the configurations appropriate to provide ancillary services are reviewed. The flexibility and features provided by the power electronic interface are illustrated. In addition to control of the real power, other functions can be incorporated into the design of the interface to provide services, such as reactive power, and resources associated with power quality. These include voltage sag compensation and harmonic filtering. The implications on the design of the power converter interface are discussed.read more

Distribution system voltage regulation under fault conditions using static series regulators
K. Haddad,Geza Joos +1 more
Abstract: Power quality and availability are becoming important issues for critical and sensitive loads. Many of the disturbances are caused by faults on the utility distribution system in one or more phases, resulting in voltage dips and sags. This paper presents a viable alternative to UPS solutions to three phase load support in the form of practical series compensator structures. The compensators consist of transformer coupled voltage source inverters fed from a single diode rectifier connected to the faulted AC supply. The balancing and regulating algorithms are developed and applied to partial and total single phase to three phase type of faults. The compensation capability of the proposed schemes are derived. Practical issues, such as design, converter rating and the relative merits of each topology are considered. The paper also provides experimental results for a 2 kVA prototype power conditioner.
