The aim of this paper is to implement a modified Perturb and Observe algorithm (P&O), in order to solve the oscillations problem of photovoltaic (PV) power output generated by the conventional P&O algorithm. A comparison between the novel and the basic P&O algorithms is made. The first is implemented using embedded C language; the second is implemented using analog blocks. Next, the simulation...
Because of the current power grid limitations, the Smart Grid is proposed as a promising alternative. It supports green energy resources and enhances power generation, delivery and distribution. For better energy management, extensive data exchange between subsystems and the control plane is needed. Since the Smart Grid uses existing technologies for communication, it inherits their defects. Targeting...
Accurate control of the wind turbine at its optimal rotational speed for a given wind speed is required to extract maximum power from the wind turbine generator system in the absence of aerodynamic pitch control. Due to inherent wind turbine nonlinearities and unpredictable wind speed fluctuations, precise control is a difficult task to undertake. This paper presents a sliding mode speed controller...
The electric power distribution system of solar system delivers power to the customers from a set of distribution substations. While the transmission lines are configured in a meshed network, the distribution feeders are configured radially in almost all cases. The proposed problem in this work is to determine the optimal topology among a various alternatives. This problem is known as a problem of...
For the best exploitation of various renewable energy resources, it is important to improve the efficiency and reliability of the GPV photovoltaic systems. The maximum power point tracking (MPPT) has an important role in the performance of the photovoltaic power systems. We present in this paper a new technique of control bazed on the fuzzy logic algorithm for solar panel. The GPV photovoltaic systems...
In recent years the development of photovoltaic cells has increased due to the high demand for clean and green energy. Used around the world for energy production, the power production of these cells must be maximized in all weather conditions, therefor systems for tracking the Maximum Power Point became necessary, the most widely used being Perturb & Observe. Fuzzy Logic (Type 1 & 2) was...
