“…As such, the types of services that may be provided are only the ones that fit with the TES characteristics. In particular, with respect to electrical energy storage, which can provide relatively fast services at sub-second time scale, e.g., for power quality improvement, grid stability enhancement, and short-time backup power [22,23], a TES system has slower response due to its intrinsic thermal capacity that affects the thermal transients [24]. At the same time, heat (or cooling) cannot be stored for a long time, because of the thermal losses due to the difficulty in insulating the storage devices.…”

Thermal energy systems (TES) contribute to the on-going process that leads to higher integration among different energy systems, with the aim of reaching a cleaner, more flexible and sustainable use of the energy resources. This paper reviews the current literature that refers to the development and exploitation of TES-based solutions in systems connected to the electrical grid. These solutions facilitate the energy system integration to get additional flexibility for energy management, enable better use of variable renewable energy sources (RES), and contribute to the modernisation of the energy system infrastructures, the enhancement of the grid operation practices that include energy shifting, and the provision of cost-effective grid services. This paper offers a complementary view with respect to other reviews that deal with energy storage technologies, materials for TES applications, TES for buildings, and contributions of electrical energy storage for grid applications. The main aspects addressed are the characteristics, parameters and models of the TES systems, the deployment of TES in systems with variable RES, microgrids, and multi-energy networks, and the emerging trends for TES applications.

“…In addition, a multi-time electricity price response model based on user behavior and satisfaction is established, and the core value of the model ia to describe the mechanism and effect of participation in electricity price demand response. In [36,37], the applied DR in a multi-carrier energy system (thermal and electrical) leads to decreasing the emission, but the parameters of MCP and DP are in considered in the model. In addition, in [38][39][40], respectively, a DR solution to economic operation issues of grid-connected micro-grid and optimal renewable planning model in conjunction with DR are presented.…”

The Impact of Demand Response Programs on Reducing the Emissions and Cost of A Neighborhood Home Microgrid

et al. 2019

The desire to increase energy efficiency and reliability of power grids, along with the need for reducing carbon emissions has led to increasing the utilization of Home Micro-grids (H-MGs). In this context, the issue of economic emission dispatch is worthy of consideration, with a view to controlling generation costs and reducing environmental pollution. This paper presents a multi-objective energy management system, with a structure based on demand response (DR) and dynamic pricing (DP). The proposed energy management system (EMS), in addition to decreasing the market clearing price (MCP) and increasing producer profits, has focused on reducing the level of generation units emissions, as well as enhancing utilization of renewable energy units through the DR programs. As a consequence of the nonlinear and discrete nature of the H-MGs, metaheuristic algorithms are applied to find the best possible solution. Moreover, due to the presence of generation units, the Taguchi orthogonal array testing (TOAT) method has been utilized to investigate the uncertainty regarding generation units. In the problem being considered, each H-MG interacts with each other and can negotiate based on their own strategies (reduction of cost or pollution). The obtained results indicate the efficiency of the proposed algorithm, a decrease in emissions and an increase in the profit achieved by each H-MG, by 37% and 10%, respectively.

“…In Reference [13], the cooperative operation of electric boiler and thermal power plant is used to improve the system's ability to accommodate wind power. A scheduling model based on CHP, heat storage device, and demand response is proposed in Reference [14]. To further increase the ability to accommodate wind power, the coordinating operation method is proposed among the heat storage device, CHP unit, heat storage device, or pumping energy storage in References [15,16].…”

A New Wind Power Accommodation Strategy for Combined Heat and Power System Based on Bi-Directional Conversion

et al. 2019

View full text Add to dashboard Cite

The extensive use of wind power can not only reduce dependence on fossil fuels, but also reduce emissions of polluted gases. However, large-scale wind power curtailments often occur in northeast China during the heat supply season, due to the fact that most of electrical demand is covered by the electrical power of the combined heat and power (CHP) during the off-peak hours. At present, for northeast China with heating demand, most of the research only focuses on how to accommodate more wind power on the spot by using one-directional conversion of the electric and thermal energy. But it is still difficult to realize the bi-directional conversion between the electro-gas or electro-thermal energy. In this paper, a combined electro-gas bi-directional conversion system (CEGBCS) is established by adding the power to gas (P2G), fuel cell and heat storage device in CHP system. This CEGBCS can not only realize bi-directional conversion of the electricity and gas, but also decouple the two operation modes of CHP unit, which greatly improve the ability of system to accommodate additional wind power. Finally, the effectiveness of the proposed CEGBCS is verified by comparing with two traditional methods.
