Summary In view of the current problem of severely abandoning wind and photovoltaic in the wind‐photovoltaic‐hydro‐thermal‐energy storage, a multi‐energy complementary coordinated dispatch method for the integrated system of wind‐photovoltaic‐hydro‐thermal‐energy storage is proposed. First of all, the power output of wind and photovoltaic is simulated using the improved Markov chain. Secondly, the load demand, the minimum economic output of thermal power units, and the force output of hydropower units are determined. The feasible operation region of renewable energy power generation is also calculated. Then, the power generation of wind and photovoltaic is prioritized within the feasible operation region of renewable energy power generation. On this basis, the dispatch strategy of hydropower is formulated according to plan for water. Finally, aiming at the minimum cost of thermal power units and life attenuation comprehensively of energy storage within dispatch period, the dispatch strategy for thermal power units and energy storage is proposed. The particle swarm algorithm is used to solve the optimal objective function. The instance shows the correctness and validity of this method.

“…A hybrid system is a combination of one or more resources of renewable energy such as solar, wind, micro/minihydropower and biomass with other technologies such as batteries and diesel generator [8,[15][16][17][18][19][20][21][22][23][24][25][26][27][28][29][30]. The hybrid system studied in this work is one combining solar PV and wind turbine with diesel generator(s) and bank of batteries, which are included for backup purposes.…”

Abstract:Shortage of electric power is a serious problem in Ethiopia. The population living in urban and semi urban areas connected to the national grid makes only less than 20% of the total. The remaining 80% of the population in scattered rural villages and have very remote chance to get electricity from the grid. The only realistic approach to electrify the rural areas seems therefore to be the off grid system. Study was conducted to assess suitability of stand-alone wind-solar PV hybrid power for Debmel village which is detached off the main grid line. The data required for this work (wind speed and sunshine hours) were obtained from the National Meteorological Agency (NMA) and analyzed using HOMER & MATLAB software's. The actual data used was from Dire-Dawa station, which is the closest meteorological station to the village. Both wind power and solar PV power potentials were evaluated from wind speed and sunshine hours of the station, respectively. The electrical load for a model community is considered and a community school together with a health post is included. For the feasibility study of the hybrid system HOMOR is used. By running the software the optimization results have been generated and arranged according to their least net present cost. Furthermore, a sensitivity analysis also carried out for the major sensitivity components of the hybrid system (like PV price, hub height and diesel price). The study revealed that the area has abundant solar energy potential (6.12 KWh/m 2 /day) but its wind potential is not as promising. This is partly attributed to the level at which wind speed measurement was taken, 2 m, instead of the recommended 10 m height. The result of the software shows that the most cost effective system, i.e. the system with the lowest net present cost, is the PV-generator-battery-converter setup. For this set-up, the total net present cost (NPC) is $ 155,875, the cost of energy (COE) is 0.415$/kWh, contribution from renewable resources is 91%.

Abstract. This paper is within the framework of the GISER (Gestion Intelligent des Systèmes d'Energies Renouvelables). It's a project about 3kVA hybrid energy management in PERE Laboratory (Procedés des Energies Renouvelables) of EST fez Morocco. We present a sizing study and a cost analysis of a photovoltaic system using simulation results with Sunny Design software. The goal of our work is to compute and optimize the dimensioning of a photovoltaic installation in order to find the best configuration of the system. We have considered a PV installation connected to the grid with 2.5kWp through an inverter. We have taken into account meteorological conditions in the installation site (radiation and temperature). Our optimization approach considers the operation of each part of the installation, including energy production, energy consumption and the overall quality/price of the installation. IntroductionThe rapid depletion of fossil-fuel resources on a worldwide basis has necessitated an urgent search for alternative energy sources. Photovoltaic and wind energy are considered as promising toward meeting the continually increasing demand for energy. The solar energy is inexhaustible and pollution-free. With the growing world population, electrical network become nonoperational due to redundant and overstressed infrastructure. Micro-grids are a promising solution to provide local energy generation and management [1]. Generated energy from PV systems depends mainly on solar energy available at selected site. Geographical location, ambient temperature, clearness index, tilt angle and orientation of PV panel. In order to efficiently and economically use of PV array system sizing and economic analysis is necessary [2]. Several researches, deal with system cost optimization of either grid-connected or stand-alone using HOMER optimization software which is based on the analytical simulation and storage system with anaerobic digestion biogas Power Plants [3]- [5]. Others [6][7] have developed heuristic methodologies, relying on evolutionary algorithms to optimize micro grids or HRESs size according to cost, environmental, or reliability parameters. However, few of them deal with solar-, wind-, and biomass-resource hybridization in a grid-connected scheme [8] -[11]. In [12] the authors showed that the Moroccan climate is very favorable for the installation of gridconnected microgrid in several regions of the country. In [13] a grid coupling and injection into isolated grid networks with a proposed method to eliminate the first harmonics using a multilevel inverter. The photovoltaic systems, particularly those linked to the grid, have been developed in reply to an increasing demand of a renewable and clean energy [14], the aim is that the system must be economically attractive, the components for PV installation have a great influence on the system cost and its lifetime, and thus each part of the system must be well optimized and configured [15] [16].
