“…From Table 3, it can be observed that the CPU time of TSCO algorithm is much less than all other compared algorithms. In addition, the TSCO algorithm obtains less fuel cost than the algorithm reported in the existing literature, 5,10,12,16,20,28,29,33,[35][36][37] and almost equal fuel cost with the CSO 35 algorithm. As shown in Table 2, the power production and the heat production are 600.6834 MW and 150 WMth, respectively.…”

Summary Combined heat and power economic dispatch (CHPED) problem is a sophisticated constrained nonlinear optimization problem in a heat and power production system for assigning heat and power production to minimize the production costs. To address this challenging problem, a novel social cognitive optimization algorithm with tent map (TSCO) is presented for solving the CHPED problem. To handle the equality constraints in heat and power balance constraints, adaptive constraints relaxing rule is adopted in constraint processing. The novelty of our work lies in the introduction of a new powerful TSCO algorithm to solve the CHPED issue. The effectiveness and superiority of the presented algorithm is validated by conducting 2 typical CHPED cases. The numerical results show that the proposed approach has better convergence speed and solution quality than all other existing state‐of‐the‐art algorithms.

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

et al. 2019

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.

“…In terms of extraction condensing unit, although its production of electricity and heat are also coupled, it has a more flexible heat-power generation characteristic compared with back-pressure turbine. A typical heat-power feasible operation region [27] for an extraction condensing CHP unit is shown in Figure 3. The power and heat outputs are constrained in the quadrilateral ABCD.…”

Wind power has achieved great development in Northern China, but abundant wind power is dissipated, rather than utilized, due to inflexible electricity production of combined heat and power (CHP) units. In this paper, an integrated CHP system consisting of CHP units, wind power plants, and condensing power plants is investigated to decouple the power and heat production on both the power supply side and heat supply side, by incorporating electrical energy storage (EES) and thermal energy storage (TES). Then the integrated CHP system dispatch (ICHPSD) model is formulated to reach the target of reducing wind power curtailment and primary energy consumption. Finally, the feasibility and effectiveness of the proposed ICHPSD model are verified by the six-bus system, and the simulation results show that EES has a better effect on wind power integration than TES. The annual net benefits by incorporating EES and TES increase with increasing wind penetration, but they gradually approach saturation. Introducing both EES and TES can largely increase the amount of wind power integration and improve the operation efficiency of the system. Energies 2016, 9, 474 2 of 17 technologies which are suitable for large-scale applications, conventional battery storage is efficient but the investment would be very high. Pumped hydro is fit for large-scale applications but it is applicable only in certain locations [11]. Nowadays, hydrogen storage is emerging as a promising alternative due to high energy density, clean fuel, and relatively low capital cost [12,13]. Adding hydrogen storage to a CHP system could improve the accommodation of wind power, as well as primary energy saving, since the wind energy curtailed in off-peak hours could be used to split water into hydrogen and oxygen. Hydrogen would be stored and then transformed to electrical energy, when necessary, by various ways.Thermal energy storage (TES) is another attractive option for wind energy integration. Although thermal storage is not directly related with electrical energy production, introducing TES is an efficient solution to relieve the mismatch between heat/power demand and supply, by decoupling the generation of electricity and heat [14]. The surplus thermal energy is stored during the operating periods for a later use when electrical demand is low, leading to a decrease in heat production of CHP plants, along with a reduction in electricity production, as a result, wind power would be better integrated. Under the influence of real-time electricity pricing, a large number of TES units have been installed in European countries which have a large percentage of wind power [15]. For example, in Denmark, TES systems have been an important part of its 100% renewable energy system plan [16].Many studies have been involved in the flexible operation of integrated CHP systems recently. In [17], heat pumps and thermal inertia of buildings and thermal comfort of end users are considered to increase the wind power integration. In [18], electric boilers and heat storage tanks are...
