Optimal allocation of a hybrid photovoltaic‐basedDGandDSTATCOMunder the load and irradiance variability

Abstract

Summary This paper addresses the allocation of a hybrid system that includes PV‐DG and DSTATCOM. The planning problem considers the variations of load demand and solar irradiance under deterministic and probabilistic conditions. An efficient optimization algorithm called MPA is implemented to assign the optimal placement and ratings of the hybrid PV‐DG and DSTATCOM. The considered objective function is a multi‐objective function that includes the annual cost reduction, improvement of voltage profiles, and system stability improvement. The assessment is accomplished with the inclusion of a single and two‐hybrid system on a large 94‐bus system. For validating the effectiveness of the MPA, the yielded results are compared with the PSO, which is considered a commonly used algorithm. In deterministic conditions, the hourly variations of the load demand and solar radiation are considered in four yearly seasons, while in probabilistic conditions, 3 years of hourly historical data of solar irradiance and load demand are utilized to describe the uncertainties of the load demand and solar irradiance. The simulation results demonstrate that the optimal inclusion of a single‐hybrid PV‐DG and DSTATCOM system can enhance the system's technical performance (the voltage profile, the voltage stability) and enhance the economic scheme (total annual cost reduction). In addition, the inclusion of two‐hybrid systems is superior compared with the inclusion of a single‐hybrid system in terms of the considered objective functions, as well as the proposed technique is more efficient for solving the allocation problem of the hybrid system.

Energy Management of Microgrid With Renewable Energy Sources: A Case Study in Hurghada Egypt

“…In their review, the authors in [19][20] looked at EM techniques for combined natural energy sources. The proposed strategy in this paper is a mixed-generation clean energy system (more than one renewable source) using a battery as a storage (or diesel generators) due to considerable dependence on climatic and meteorological factors [21]. Hybrid energy systems are widely used to expand the grid to deliver electricity for a wide range of applications [22,23].…”
