“…In line with previously provided research by authors in [1], a lot of measures are proposed to improve the operation of cogeneration power plants. That is why, firstly, it is necessary to evaluate the level of CHP plant operation by assessing bottlenecks, which should be improved.…”

“…The running conditions of cogeneration power plants have changed from base load operation to running conditions in cyclic modes due to implementation of market mechanisms, feed-in tariffs for renewable energy sources (RES) and large-scale integration of RES in energy production process [1], [2]. As an example, the changes in Riga CHP-2 plant generation profile are reflected in Figs.…”

“…There are two solutions: (1) to mothball power plants or (2) to keep on operation after implementation of appropriate measures. The second option is more logical than the first one, taking into account the benefits of cogeneration power plants and the forecasted increase of them [1]. Moreover, it is impossible to ensure the secure energy supply and provide the successful integration of intermittent renewable energy in energy production process without CHP plants [3].…”

“…The measures concerning cogeneration power plants at the operation stage are going to be presented. They were divided into five groups by the authors in [1]: (1) equipment upgrade; (2) storage opportunities; (3) operation optimisation; (4) new installations; and (5) competitiveness increase.…”

Intermittent generation (solar PV and wind energy) integration in power production portfolio as well as electricity price fluctuations have changed the running manner of conventional combined heat and power (CHP) plants: the shift from base load operation to running in cyclic modes. These cogeneration power plants are not adapted to new running conditions. The level of CHP plant flexibility should be improved to operate profitably and efficiently from both technical and fuel usage point of view. There are different ways to increase the flexibility of power plants. Before any improvements, the situation at power plants should be evaluated and the weakest points defined. In this publication, such measures are presented on Riga CHP-2 plant example: installation of heat storage tank; extension of operation rang; acceleration of start-ups.

The implementation of the market mechanism, which includes electricity price fluctuation, and a wide integration of intermittent generation, namely solar PV and wind energy, in energy production have changed the role and operation manner of conventional generation. It is partly or not at all adapted to new running conditions. Therefore, the efficiency and flexibility of conventional generation has to be improved. The numerical approach is developed in the context of combined cycle gas turbine (CCGT) technology to adapt its running conditions to the electricity market mechanism. The developed approach was verified on a case study of the Baltic States (Latvia) examples in a multi-paradigm numerical computing environment MATLab. The obtained results show that the added profit is gained through production of supplementary electricity, and the impact of cycling operation is reduced through the decrease of cycling operation ranges numbers and the substitution of start-up with a less adverse one from a technical and economical point of view. The developed approach can be adapted to various technologies and situations by adding appropriate characteristics and constraints of technology.
