The main problem which often occurs in wind turbine systems is getting the maximum power output and maintaining the DC link voltage at a constant value through wind fluctuation. This paper proposed to maintain the DC link voltage during stand-alone condition, it takes a battery as energy storage with a bidirectional buck-boost converter to regulate charging and discharging mode, alternately. Control...
The use of wind energy as a source of electrical energy is increasing along with the limited fossil energy and increase environmental awareness to the greenhouse effect. This paper presents the modeling and control of permanent magnet synchronous generator (PMSG) for wind turbines. To get optimal power, the generator must be able to rotate at the optimum speed so that it is required speed controller...
Nowadays, wind energy, as a source of electrical energy, are growing rapidly to substitute fossil energy. The power generated wind turbine is fluctuating that is influenced by wind speed so that it takes the appropriate controlling to get the maximum energy and the constant power for grid. This paper presents control for variable speed permanent magnet synchronous generator (PMSG) wind turbine that...
To increase efficiency of wind power system, the system have to work at maximum power. This paper proposes a new modification of the algorithms firefly by updating the coefficient p and neglected α and γ to get the maximum power from the wind turbines use a permanent magnet synchronous generator. The method differs from the standard firefly just ignore α and γ to accelerate convergence alone. The...
The selection of site wind farm is an important element in building a wind power generation to get a site that is capable of produce maximum energy, economic and environmental agreeable. It is obtained if proposed alternative sites has continuous wind resources, access to the grid, good topography, land costs are cheap, reduce noise blade and available road access. The site proposed of study is Sukomoro,...
To overcome the limitations of fossil energy and protect the environment from emissions of greenhouse gases, it is essential to develop the use of renewable energy as a substitute. At present, one of the renewable sources of energy is wind energy, which has the advantage of being pollution free and inexhaustible. However, the use of wind energy is strongly influenced by wind speed, which is not constant...
Solar energy is a potential energy source in Indonesia.A photovoltaic is needed to harvest this kind of energy, and to be able to gather the most, the PV must have a good efficiency. The maximum efficiency is achieved when PV works at its maximum power point which depends on irradiation and temperature. Since the irradiation and temperature always change with time, a PV system which able to track...
PEF is the newest non thermal technology for liquid and semi-solid food processing system. Based on previous researches, PEF has the advantage of maintaining better nutritional products, compared with the thermal system. PEF pasteurization requires a high voltage pulse generator that produces electrical shock. Some researches had been conducted to develop a generator circuit which has high efficiency...
This paper presents a digitally-controlled paralleled DC-DC converter. The main objective of the digital control is to achieve load sharing while operating at close to peak efficiency over an extremely wide load range. Results from computer simulations using Simulink show the digital control could indeed accomplish the objectives, but the improvements over a single converter depend on the original...
