An Enhanced Approach for Solar PV Hosting Capacity Analysis in Distribution Networks

Abstract

With the falling cost of Distributed Energy Resources (DERs) and the shift from fossil fuel to renewable energy in many countries, the integration of DERs is expected to grow. This can lead to a wide range of problems in the power system, such as voltage violations, overloading of distribution lines, reverse power flow, etc. Therefore, it is imperative to account for these adverse effects of the integration of DERs on the distribution network and minimize their impact when calculating the Hosting Capacity (HC). Two algorithms are presented in this study derived from a novel modified iterative method and a novel Repeated Particle Swarm Optimization (RPSO) method for determining the HC for multiple DER units simultaneously or a single DER unit integrating into radial or mesh networks. These algorithms calculate the optimal HC based on six scenarios of annual load and DER generation profiles. The developed algorithms were tested on the IEEE 123 bus network, and their results were compared. For a large-scale DER case, the modified iterative method significantly outperforms both the PSO and the normal iterative method in terms of computation time (30 minutes versus 3 hours versus 6 hours, respectively). In the case of multiple DERs, the RPSO method is the only option, as the other two methods cannot simultaneously optimize multiple DERs. As a result, it has been concluded that it is necessary to select HC calculation methods carefully and in accordance with the application, as each method has its own strengths and weaknesses.

An Improved Analysis of Distributed Resource Access Location and Capacity on Voltage Stability of Distribution Networks in Smart Grid

“…They can also be used to calculate the highest possible benefit that can be attained through parameter optimization, including configuration, location, and PV capacity. The upgraded approach for solar PV hosting capacity study, as described by Abideen, M. Z. U., et al [25], makes use of cutting-edge technology and algorithms to calculate the maximum quantity of solar PV that a distribution network can take without having negative effects. In order to produce more precise and trustworthy findings, this method considers a number of variables, including voltage and thermal limitations.…”

A Combinatorial Double Auction for Community Shared Distributed Energy Resources

“…Where d g i is from (7). Constraint 8a ensures that the energy provided by DER does not exceed demand.…”

“…These limitations coupled with the high investment and space requirements of small-scale (1-10 kW) individually-owned DERs have promoted the investment in medium-scale (10-100 kW) community shared DERs [3]. Unlike the uncontrollable smallscale DERs, Community shared DERs can also limit some of the technical challenges of DER integration, which include voltage violations and overloading of distribution lines [7]. Investing in community shared DERs can also open the opportunity for economies of scale, which can further cut down the costs of DER integration.…”

Application of Photovoltaic Systems in Field Observation and Research Stations: Research on the Relationship between Power Generation Scale and Electricity Consumption to Improve Photovoltaic Application in Field Observation Stations

“…Ahmad et al used OMER software to discuss the optimization and implementation of institution-based sustainable microgrids from the cost analysis, carbon emission, energy availability, and other aspects of the campus network [4]. Abideen et al [5] study proposed two algorithms from a new improved iterative approach and a new repeated particle swarm optimization (RPSO) approach and calculated the optimal hosting capacity based on six annual load and distributed energy resource generation scenarios. In recent years, different sizing methods and a simulation software have been widely used for the design and analysis of photovoltaic power systems.…”
