ABSTRACT
Noncentralized techniques, in turn, can be either decentralized or distributed. It can be concluded that decentralized technique relies only on local information and does not need any components other than interface converters. This chapter considers the problems of tracking voltage synchronization in multiple photovoltaic (PV) and multiple wind generator systems. All generator systems must act as one group to achieve synchronization through local information exchanges. The chapter examines sampled-data measurement and time-triggered zero-order-hold and provides a numerical example. It presents modeling of multi-PV generators with alternative current load and direct current load. The chapter also presents multi-machine wind generators with direct current load and alternative current load.
