“…Every system component is represented within detailed models. The reasons for performing the studies in ATP are as follows [26], [27]: 1) network protection cannot be represented by commercial loadflow tools; 2) the mechanisms of switching and protective devices cannot be properly modeled in other tools (under-and over-voltage protection of DGs); 3) the DG model is not as detailed in other tools as those in ATP. The DG and load models are represented explicitly in ATP simulations.…”

Abstract-This paper presents an overall analysis of how the penetration of distributed generation in low-voltage secondary distribution networks affects voltage stability. It is critical that the voltage collapse point be carefully studied under different system operating points to prevent degradation of service. System components have been sophisticatedly modeled in ATP/EMTP. DGs are allocated in a probabilistic fashion to account for uncertainties in future allocation. A large number of experiments under both light and peak load conditions have been carried out to provide realistic results. Results indicate that voltage stability is positively correlated with penetration of DG, but large induction type DG may lower the voltage stability margin.Index Terms--Distributed power generation, power systems, power system stability, reactive power, smart grids. I. INTRODUCTIONDistributed generation (DG) has become an increasingly important source in the modern power grid. Although the cost of installation is high, DG benefits the customers by providing electricity endemic to the customer rather than at a distant generator. Therefore, DG can help to reduce the demand at peak times so that power congestion may be minimized preventing degradation of service. Yet, research efforts reveal that there are challenges that DG poses to the safe and reliable operation of distribution systems [1]- [16].To provide optimal reliability to customers, in case of multiple contingencies, the meshed low-voltage (LV) secondary networks are applied to major metropolitan areas and business districts. There is more effort involved in interconnecting DG with meshed networks compared to radial ones since the operation strategies are different [17], [18]. For instance, in meshed networks the reverse power flow from LV networks to medium-voltage (MV) networks is forbidden, which means the network protection will be tripped if the power flows from secondary side to primary side. Significant research effort has been invested in elucidating the advantages and disadvantages of DG for radial networks [29]. However, because of the characteristics and constraints of mesh networks, it would be difficult to implement certain optimization strategies for DG allocation. Therefore, a probabilistic approach is proposed based on the relationship between customer demand and DG parameters (type, size, and location) [26], [27]. In this paper, a probabilistic approach to allocation will be applied.In the 1990s the voltage stability problem became an interesting topic for transmission networks and was extensively studied [30]-[32]. Recently, with the advent of new DG technology, voltage stability studies have been extended to distribution networks [33]. In this paper the longterm voltage stability will be considered to reveal the the system's ability to maintain steady voltage profiles following small disturbances experienced through continuous variations in load [34]-[36].In this paper, we present a comprehensive analysis of how the penetration of DG may affect th...

-The present trend of increasing the penetration levels of Distributed Generator (DG) in the distribution network has made the issue of Islanding crucial for the reliable operation of the network. The islanding, if not detected early may lead to the collapse of the system as it can drive the distribution system to the cascaded failure. In this paper, an extensive study of the effect of DG placement and sizing is performed by dividing the system into different zones to obtain a reduced effect of islanding. The siting and sizing of DG is carried out to improve the overall voltage profile or/and reduction in active power loss using two stage Genetic Algorithm (GA). In the first stage a basic knockout selection is considered and the best population is taken for next stage, where roulette selection for crossover and mutation is performed for optimal placement and sizing of DGs. The effect of the islanding, due to load variations is reduced by optimal siting and sizing of DG. The effectiveness of the proposed scheme is tested on the IEEE 33 and 69 radial bus systems and the results obtained are promising.

Abstract-The paper solves a distributed generations placement problem considering loss and cost of DG as the main objectives while power quality issues like voltage magnitudes at different bus and harmonic distortion are maintained within some specified limits as per IEEE standards. To study the effect of several factors on DG placement the issues are considered individually first. Then the same problem is solved considering all the issues together. It has been shown that when all the issues are considered the harmonic distortion plays a vital role in deciding the DG locations and size. Again the harmonic distortions are more near to the harmonic generating loads. The shunt compensation is also included to improve the voltages to a specified limit.Index Terms-Distributed generations, genetic algorithm, harmonic distortion, power quality, renewable energy.
