This paper presents analytical methods for optimum allocation of distribution generators in a radial distribution network. The aim is to increase power efficiency and reduce loss of power. The ideal size of each distribution generator unit at the identified locations has been carefully selected by making adjustments to loss saving equations and the voltage on a radial feeder. The experimental system is located in the governorate of Bethlehem specifically within the district served by the Jerusalem Distribution Electricity Company (JDECO). The NEPLAN simulator has been utilized in the verification process of the aforementioned experimental system. It entails of several nodes and 400 V-buses that feed up to five household loads. The size and location of each has been carefully chosen. Consequently, significant loss saving, and voltage profile improvement have been reported. Hence, the use of Renewable Distribution Generators (DGs) systems is highly desirable for various reasons including increased system reliability, decreased loss of power, and enhanced voltage profile. Notably, cutting back on the use of conventional fuel will in turn reduce the negative environmental impacts.

The three-step rule of distributed photovoltaic (DPVs) connecting to a distribution network in the planning of practical photovoltaic projects is modeled in this paper. On this basis, a method based on large sample historical generation-load data is proposed to comprehensively evaluate the DPV limit penetration level of the low voltage–medium voltage (LV-MV) distribution network, which is the premise of DPV connection planning. Considering the fluctuations of generation-load data in time and space, the DPV limit penetration level of the LV network is evaluated based on kernel density estimation. On this basis, considering the uncertainties of DPVs connecting node schemes and connection capacity, the limit penetration level of DPVs continuously connecting to the MV network is evaluated based on the dichotomy method and stochastic simulation. Finally, the feasibility of evaluating the DPV limit penetration level by the proposed method is verified based on an example of a real distribution network, which is of great importance for the planning of a distribution network with high DPV permeability to continuously connect to DPVs.

Summary The recent changes in distribution systems have challenged utilities to assess the unprecedented volume of photovoltaic (PV) generator connections, which can result in adverse technical impacts from voltage rise and conductor overload. Therefore, a fast and effective way to analyze a distribution system's capacity to host new PV generators is crucial for the utilities. Usually, the connection assessments are based on repetitive power flow and short‐circuit calculations, and even though these analyses can be accurate, they require a steep increase in person‐hours and processing time. A simpler way to identify the hosting capacity of distribution systems to the connection of new PV generators is the adoption of connection assessment tools that, if properly designed, allow utility engineers to evaluate quickly if a new PV generator can be connected or not. This work proposes a connection assessment tool based on a fast screening approach that allows utility engineers to graphically analyze if a rooftop PV can be connected to a distribution system without causing adverse impacts. Tests of the proposed method are performed in two real distribution systems, attesting to its efficiency.
