SUMMARYThis paper deals with load side management strategy for (photovoltaic-wind-diesel) hybrid system for medium rural health building located in the Sahara region. The paper presents an overview about geographic and climate data of the location and develops a typical load profile of electrical energy, depending on a real investigation of daily electricity consumption. The base of the proposed management strategy is the control of the air conditioning system and the non-critical lighting of the building as they consume more than 50% of the total power consumption. The result shows that the reduction in the peak consumption is about 20% using the proposed management strategy, which has significant economical, technical, and environmental benefits.

“…The aim of this study was to minimize total net present cost as well as minimize cost of energy, maximize renewable energy ratio, and reduce fuel emission all together under a conditioned level of loss of load probability. Two studies of the micro-grid effect on the decreasing of cost through improving the reliability of small scale distributed generators using different optimization techniques were exhibited [37,38].…”

Optimization of renewable energy-based micro-grids is presently attracting significant consideration. Hence the main objective of this chapter is to evaluate the technical and economic performance of a micro-grid (MG) comparing between two operation modes; stand-alone (off-grid), and grid connected (on-grid). The micro-grid system (MGS) suggested components are; PV panels, wind turbine(s) inverter, and control unit in case of grid connected. In the stand alone mode diesel generator and short term storage are added to the renewable generators. To investigate the performance of the MGS; technically, detailed models for each component will be presented then the complete MGS model is developed. Another objective of this study is the economical evaluation of MGS by comparing the system net present cost (NPC) and cost of generated electricity for the two modes of operation; off-grid and on-grid. applications and REMG. This requires fulfilling the signed purchase power agreement (PPA), through regular payments and ability of transferring their revenues of selling electricity to dollar.

“…In other words, the active power delivered to the utility grid on a maximum value with unity power factor or no reactive power generated/absorbed by the system. A number of the literature agreed [5][6][7][8] that in order to optimize the delivery of electrical power from the inverter to the grid is done by setting the output voltage of the inverter and the angle angle.…”

The application of solar power plants connected to the utility grid could be one solution in reducing the use of fossil fuels as primary energy power plants.Currently, the use of solar energy to supply electricity on the on-grid area is growing rapidly. This paper proposes a simple method to optimize the power delivery of photovoltaic (PV) system to the utility grid. Two variables, the inverter output voltage V int and power angle , is determined from the roots of two simultaneous Eq., active and reactive power in order to find the maximum and minimum reactive power. Newton Raphson method used to solve the roots of the two Eq. simultaneously. The value of V int corresponding to the root equation is done by adjusting the amplitude modulation of the inverter.Hence, the set is done by shifting the phase angle of the reference wave of the inverter. In this model, 10 PV modules type of ND T060M1 with a 60 Wp capacity are used. The simulation results using SIMULINK-MATLAB have a pretty good performance. The voltage at the PCC point has reached its stable value at 220Volt . Simulation results have shown the maximum value of the active power system at 1000 W/m 2 irradiation was 408 W, as the reactive power is needed only 11. 82 Var. The solar power can work in a power factor approaching unity with the application of the proposed method is suggested.
