1. Introduction The technical, economic and environmental feasibility of micro-cogeneration plants –according to the cogeneration directive published in 2004 [1], cogeneration units with electric power below 50 kW e – in the residential sector is intimately tied to the correct sizing of micro-CHP and thermal energy storage systems, as well as
In [19], the maximization of economic indexes are evaluated to obtain a hybrid plant, but with PV generation and storage, which is the only asset to be sized. In [20], the problem of optimal
Abstract The emergence of the shared energy storage mode provides a solution for promoting renewable energy utilization. However, how establishing a multi‐agent optimal operation model in dealing with benefit distribution under the shared energy storage is
3. Operation strategy. The operation strategy consists of three separate parts: (1) forecasting of wind velocity, (2) scheduling of the power exchange with the market and, (3) on-line operation of the storage. In the present model, the forecasts of load and spot price are assumed to have 100% accuracy.
Section snippets System description The distributed resource is presented in Fig. 1, and consists of a wind power plant and an energy storage device. The owner of the resource is assumed either to have a demand for electricity P l or, alternatively, to have contracts with nearby electricity consumers represented by an aggregated load demand.
On Tuesday, 17 October 2023, at the City Hall, we and our partners signed a contract for the project titled Green energy on the surfaces and facilities of the City of Ljubljana, within the framework of which we will set up solar power plants on the facilities in the ownership of the City of Ljubljana.
Given the prevalence of fossil fuel plants in modern power systems, CCOS offers a viable means to mitigate the pollution from this sector [21]. Through partial utilization of the plant-generated energy, CCOS reduces CO 2
This chapter presents the recent research on various strategies for power plant flexible operations to meet the requirements of load balance. The aim of this study is to investigate whether it is feasible to integrate the thermal energy storage (TES) with the thermal power plant steam-water cycle.

Slovenia''s government plans to co-finance the construction of waste-to-energy plants in Ljubljana, Maribor and Kocevje, environment minister Andrej Vizjak
Selected solar-hybrid power plants for operation in base-load as well as midload were analyzed regarding supply security (dispatchable power due to hybridization with fossil fuel) and low CO2 emissions (due to integration of thermal energy storage). The power plants were modeled with different sizes of solar fields and different storage
1. Introduction As the rapid increase of renewable energy has adversely affected the stability and cost of the power system [1, 2], coal-fired power plants (or CPPs) are required to improve the flexibility of the output load to maintain the balance between power supply and demand [3].].

South of Ljubljana, the new part of non-toxic waste landfill Barje is in operation since September 2009. Wastewater treatment plant for trickle waters operates since July 2010. Constructuon of the main buildings of RCERO started in 2014.
Improving of fuel economy and environmental safety in power generation is a topical issue of modern off-grid energy. One of the ways to solve this problem is the usage of motor-generator unit with variable speed regulation, introduction and exploitation of renewable energy. However, these methods require the use of additional electric power converters.
The energy system in the EU requires today as well as towards 2030 to 2050 significant amounts of thermal power plants in combination with the continuously increasing share of Renewables Energy Sources (RES) to assure the grid stability and to secure electricity supply as well as to provide heat. The operation of the conventional
The pseudo-dynamic model is used to simulate the performance of the SAPG plant, and the TES operation model is used to control the operation process of TES system. Case studies In order to optimise the combinations of the SAPG plant with diverse TES capacity, an SAPG plant based on a 300 MW power plant has been used as case
For the determination of the energy storage efficiency it was also necessary to determine the auxiliary and standby losses, because these effects reduced the stored energy depending on storage time. These losses were included in η el during operation and separately considered during the standby or ''Off'' mode and they are listed in Section
Photo thermal power generation, as a renewable energy technology, has broad development prospects. However, the operation and scheduling of photo thermal power plants rarely consider their internal structure and energy flow characteristics. Therefore, this study explains the structure of a solar thermal power plant with a thermal
Based on the central chilled water plant of a high-rise commercial building in Hong Kong, a typical primary-secondary chilled water system is developed as the study object in this study. As shown in Fig. 1, the chilled water plant consists of three constant speed water-cooled centrifugal chillers with a rated cooling capacity of 3560 kW and a
The concept of using Thermal Energy Storage (TES) for regulating the thermal plant power generation was initially reported in [1] decades ago. Several studies [ 2, 3 ] were recently reported on incorporation of TES into Combined Heat and Power (CHP) generations, in which TES is used to regulate the balance of the demand for heat and

VPP2 is equipped with DG only, which has a weak regulation ability to follow loads. Shared energy storage system provides flexible adjustment capabilities during load peaks and valleys to reduce the cost of curtailment and reduces the operation cost by 25.91%. In addition to DG, VPP3 is only equipped with photovoltaics, whereas VPP4 is only
Experimental tests performed in a FB heated by a solar simulator have shown that the harsher closed-loop conditions induce a greater loss of reactivity. Pascual et al. [44, 45] conceptually

The flexible SCPP-CaL power plant concept has the benefits of both energy and cost-efficient carbon capture solution and energy storage capability. The investigated coal and lignite super-critical power plant concepts have 1000 MW net power output with a 90% decarbonization rate.
In the City of Ljubljana, we are successfully continuing the energy retrofits of buildings owned by us. Ten more energy retrofits were added this year to fifty-nine energy
When the M-GES plant cycles according to energy storage and power generation, the operation track is in the shape of "8", as shown in Fig. 9. The advantage of Maximum Height Control (MHC) over conventional control strategies is that it reduces the number of starts and stops of the gravity storage plant unit, thus improving the stability of
Abstract. We propose a hybrid renewable energy system—a geothermal energy storage system (GeoTES) with solar—to provide low-cost dispatchable power at various timescales from daily, to weekly, to seasonally. GeoTES with solar uses a concentrating solar power collector field to produce hot water that is injected into a

This paper systematically studies the energy management system (EMS) of M-GES plants. We establish a general M-GES state-of-charge model for the first time and propose the maximum height difference control (MHC) for EMS. To validate the effectiveness of the MHC, we use sinusoidal test power and a natural California load
