The nuclear phase-out and the increased share of renewable distributed generation implicate new challenges for transforming the electric power system into an environmentally sustainable, reliable and cost-efficient system. An important component in transforming the electric power system is the reliable substitution of large controllable power plants by small generation units (photovoltaic syste...

With the high proportion of renewable energy connected to grid, peak shaving demand surge, which needs enhance flexibility coal power with a larger support stable operation grid. At present, capacity combined heat and unit accounts for about 87 % direct dispatching coal-fired plants by Shandong The flexible ability is poor, its transformation urgent. This paper summarizes current relatively mat...

load management and cost optimization are among the important factors in trigenerationsystems and combined cooling, heating and power (cchp) systems. in this study, an innovative cchpsystem uses a gas turbine as the prime mover and has a heat recovery steam generator (hrsg) in addition toan auxiliary boiler, electric and absorption chillers. the system is tied with the bulk electric grid; to ex...

A previously-developed mechanistic energy balance model for production of biogas from the anaerobic digestion of microalgal biomass grown in open raceway systems was used to consider the energetic viability of a number of scenarios, and to explore some of the most critical parameters affecting net energy production. The output demonstrated that no single harvesting method of those considered (c...

The future distribution network comprising different energy carriers will include small-scale energy resources (SSERs) and loads, known as a Networked multi-carrier microgrid (NMCMG). This concept not only leads to an efficient reduction in operation costs, but also encompasses the energy transformation between gas and electric networks at combined nodes, as well as district heating networks. I...
