Investigate the optimal power system by using hybrid optimization of multiple energy resources software

Abstract

Increasing the effects of global pollution and the availability of renewable energy sources has push many countries to use reasonable energy sources such as wind and solar energy. This paper presents a case study of evaluating a hybrid renewable energy system by using a hybrid optimization of multiple energy resources (HOMER) software program based on the entered data available from the net for the considered location. The hybrid system consisting of a wind turbine, a photovoltaic system, a battery and a diesel generator. The simulation results are presented in a graphical curves n HOMER software. The obtained results indicate that by using the HOMER simulation program, the optimal design of the hybrid electrical power system for the considered location can be achieved which can help the designer to decide the types and number of the competent required for conducting the intending hybrid electrical power system which results in optimum output power in addition to reducing the overall operating costs.

Investigate the maximum power point of photovoltaic system at different environmental conditions

“…The calculation results of the DC converter parameters are shown in Table 1. The goal of the MPPT control is to bring the photovoltaic system to the maximum power point of the power and maintain it in the system regardless of the disturbance of the panel temperature changes, [25]. In Figure 3, the P-U characteristic is shown with the point of maximum power.…”

Simplified control system for grid-tied modular multilevel based energy storage

“…Modern power grids include alternative power sources. A lot of works focused on working point optimization for alternative power source for example [1], [2]. There are many tools [3]− [5] and instruments [6]− [8] to coordinate alternative source and power grid.…”

Voltage and frequency stabilization by fuzzy integrated droop control of a multi renewable source micro grid

“…The stability of the controller is tested when the stable DC sources are replaced with unpredictable renewable sources. The response time of the droop controller needs to be tested [5] with different operating conditions and source failures. The peak overshoots and disturbances caused by the conventional PI controller needs to be mitigated with new robust advanced control modules.…”
