Secure and long-term supplies of low-cost feedstocks are critical to the economics of biomass power plants. Provided that the distribution of electricity and heat infrastructure already exists, cogeneration plant (CHP) costs depend mainly on the investment, biomass distribution density and price as well as biomass transportation cost. On sufficiently large space it is possible to operate with the...
This paper analyzes influence of different operation regimes on CHP main electrical equipment reliability. Authors use statistics and Monte-Carlo method based simulation to evaluate influence of different operating regimes on synchronous generator, main circuit breaker and step-up power transformer reliability. Results are compared to VGB Powertech CHP fault statistic.
New running conditions of power plants — provoked by volatility of market price and integration of variable renewable energy sources (RES) into energy production process — refer to frequent start-ups (run-ups) and shut-downs, which are costly and detrimental. The procedure of run-up is more adverse than the shut-down. The optimization of start-up is an essential feature to provide operational benefits...
The paper focuses on the possibility of optimizing the district heating supply in the market conditions with constantly changing parameters and stochastic behavior of the electricity market prices, fuel prices and weather conditions. The possibilities of independent work of companies and cooperation for more benefits are also reviewed. As possibility of distributing the additional profit in the case...
