“…Typically, this applies to communities that are located in remote or islanded areas where there is no connection to the main grid infrastructure and it is not costeffective to extend the grid facilities to these regions. In addition, the use of diesel generators for electricity supply in these remote locations are proven to be high cost due to the difficult terrain which translates into high fuel transportation costs [1]. In addition, the carbon footprint of energy is also proven to be higher for the case of diesel-only solution [2].…”

In an off-grid hybrid wind-diesel-battery system, the diesel generator is often not utilised efficiently, therefore compromising its lifetime. In particular, the general rule of thumb of running the diesel generator at more than 40% of its rated capacity is often unmet. This is due to the variation in power demand and wind speed which needs to be supplied by the diesel generator. In addition, the frequent start-stop of the diesel generator leads to additional mechanical wear and fuel wastage. This research paper proposes a novel control algorithm which optimises the operation of a diesel generator, using genetic algorithm. With a given day-ahead forecast of local renewable energy resource and load demand, it is possible to optimise the operation of a diesel generator, subjected to other pre-defined constraints. Thus, the utilisation of the renewable energy sources to supply electricity can be maximised. Usually, the optimisation studies of a hybrid system are being conducted through simple analytical modelling, coupled with a selected optimisation algorithm to seek the optimised solution. The obtained solution is not verified using a more realistic system model, for instance the physical modelling approach. This often led to the question of the applicability of such optimised operation being used in reality. In order to take a step further, model-based design using Simulink is employed in this research to perform a comparison through a physical modelling approach. The Simulink model has the capability to incorporate the electrical and mechanical (Simscape) physical characteristics into the simulation, which are often neglected by other authors when performing such study. Therefore, hybrid system simulation models are built according to the system proposed in the work. Finally, sensitivity analyses are performed as a mean of testing the designed hybrid system's robustness against wind and load forecast errors.

Abstract:Hybrid photovoltaic-diesel systems are becoming more and more attractive for rural electrification in sub-Saharan Africa region. In this paper, some energy management strategies for a photovoltaic-diesel system without battery storage have been theoretically and experimentally studied. The proposed strategies are respectively based on active power control of inverters and controllable loads to ensure security operation for the system and maximize the solar energy penetration. Simulations and experiments have been performed under two different climate conditions and have been applied to an African rural load profile. All the energy management strategies developed have been implemented with the Matlab environment. The obtained results have shown the effectiveness of the proposed strategies to avoid power reserve to the diesel generator, to increase solar energy fraction, to reduce CO 2 emissions, and to ensure the system's frequency and voltage stability.

Different hybrid configurations of wind, photovoltaic (PV), and diesel systems for a village in the north-eastern region of Saudi Arabia are presented. The configurations (i) diesel only, (ii) wind-diesel, (iii) PV-diesel, and (iv) wind-PVdiesel power generation systems are designed and compared to select the optimal alternative system by considering the minimum cost of energy and least environmental impact. For sizing and optimizing the hybrid power systems, local hourly average wind speed, hourly total solar radiation, and hourly load data have been used as input. Of the four configurations investigated, the diesel only system is found to be most cost effective with an energy cost of 0.037 US$/kWh with a fuel cost of 0.067 US$/l. Among the hybrid power systems, the PV-diesel hybrid system with 1,500 kW PV capacity, equal inverter capacity, and four diesel generators each of 1120 kW capacity are found to the most economical solution with a COE of 0.038 US$/kWh.
