Abstract:In this paper stability prediction for a small biogas plant in islanded mode depending on local consumers energy consumption growth is given. Biogas plant with two cogeneration facilities and local consumers is tested for on grid and islanded operation and thus represents a microgrid. Generator and regulator modelling as well as surrounding electrical grid modelling in software package Power World Simulator are described. Expected consumption growth through the period of 20 years in microgrid area is simulated. All generator important variables, i.e. voltage, frequency, real and reactive power in case of islanded mode are examined and explained. Finally, stability prediction analysis of biogas plant and surrounding consumers for 20 years period is given.

Abstract-Nowadays one of the most important strategies in the European Union and in the World to solve energy problems is RES energy production. Many investments and financial supports are being done and implemented in many countries. However it is very relevant to have parameters and merit figures that help to evaluate the investments done and solutions implemented and that can be useful in the definition of future pathways and energy systems. In this work are calculated efficiency indicators to RES technologies for three EU's Member States, namely Portugal, Spain and Germany that are internationally recognized to have a significant role in RES implementation and integration.

“…Then, much effort has been addressed in research and development of less polluting fuel-to-energy processes such biomass conversion technologies [2], sustainable renewable energy systems such as solarbased, ground source-based and day-lighting [3] and solar en-ergy, wind energy and bioenergy [4], methods and tools to evaluate the availability of renewable energy sources [5] and investigation of CO 2 capture and storage techniques [6,7]. Additionally, in the present days, there seems still to be a long way to improve the efficiency of every step in power production process.…”

This paper presents a modelling approach for simulating tars and particulate (dust) removal in a moving bed heat exchange filter (MBHEF) in order to satisfy gas requirements of end-use syngas applications: engines and turbines. The two-dimension, adiabatic, steady-state proposed model accounts for two-phase (gas and solid) and neglects conduction and mass diffusion. Tars condensation is modelled through representative tar class lumps: phenol (class 2), naphthalene (class 4), pyrene (class 5). The model also considers tar concentration influence on the tar dew point. The filtration model is taken from literature. A sensitivity analysis is performed varying the particle size and the superficial gas velocity. Maps of temperature and tars abatement efficiency are presented. The simulation results indicate the feasibility of the use a MBHEF as tars removal equipment benefiting its advantages against others gas-cleaning methods with acceptable pollutant removal efficiencies, ranging 88e94% for ranges studied. Results also point out low gas velocities (0.5-1 m/s) and high particle size (400e700 mm) for reducing operational costs in MBHEFs with compact size.
