The course is divided into three sections and uses Australian references for examples:
In the first section, we introduce PV designers and installers to microgrids, which are increasingly recognised and valued by network providers and policymakers. We discuss the difference between microgrids, mini-grids, and embedded networks, identify a few of the regulatory implications, and suggest various practical approaches to microgrid implementation for renewable energy industry participants.
In the second part of this course, we discuss the value streams of energy storage. The use of energy storage may not always be a viable option for a client who uses the traditional means to secure energy, as current battery technologies are still relatively expensive. In this course, we explore 13 distinct value streams possible that might be derived from energy storage systems and we will explore how they are able to potentially reduce clients' expenses from the point of view of network providers, market services, and electricity end-users.
In the last section, we will talk about Distributed Network Service Providers (DNSPs), who are typically the authority granting permission for residential and commercial-scale PV system grid connection, must maintain power quality at all times for all customers. This section discusses various network protection requirements set by different DNSPs, Australian Standards and the AEMC guidelines, and suggests practical ways for installers to meet these requirements when applying for grid connection approval.
