Integration of different types of distributed energy resources (DERs) in distribution network has significant effects on voltage profile for both customers and distribution network service providers (DNSPs). This impact may manifest itself positively or negatively, depending on the voltage variation and the amount of DERs that can be connected to the distribution networks. This chapter presents a way to estimate the voltage variation and the amount of the DERs in a microgrid. To do this, a voltage rise formula is derived with some approximation and the validation of this formula is checked by comparing with the existing power {pipe}systems simulation software. Using the voltage variation formula, the worst case scenario of microgrid is used to estimate the amount of voltage variation and maximum permissible DERs. The relationship between voltage level, voltage rise, and connection cost of DERs in a microgrid is also described in this chapter. Finally, based on the worst case scenario of microgrid; some recommendations are given to counteract the voltage rise effect.
