The use of new distributed energy technologies (PV systems, fuel cells, energy storage, and electric vehicles) connected to the grid requires improvements in all interconnection standards to define the requirements that these technologies must need for safe and reliable integration with utility electrical networks. These standards address issues such as power quality and voltage limits for example. In many countries, local regulations will provide for these procedures, however when this does not occur, countries can use IEEE references such as IEEE 1366 and IEEE 1547.
