An innovative energy management framework for cooperative operation management of electricity and natural gas demands

Abstract

Introduction of the power to gas and combined heat and power technologies, has led to remarkable interdependency between electrical and gas systems. By taking advantage of this interdependency, cleaner and more efficient energy management systems could be implemented. This paper attempts to establish an innovative energy management framework which takes advantage of this interdependency and devices like power to gas and combined heat and power to simultaneously smoothen electricity and natural gas demand profiles for a year ahead. The method outperforms this task using the electricity profile valleys to reduce peak natural gas consumption and using natural gas profile valleys to shave electricity consumption peak. In this way, the stress on both networks for supplying demand in peak periods is released. The proposed method is able to achieve demand smoothness and cost reduction objectives considering penalty factors for demand variance. For this purpose, multiple integrated energy hubs are used to simulate the energy consumption of an area. The designed mixed integer linear model is handled by General Algebraic Modeling Software and CPLEX solver. The results demonstrate that by applying the proposed method, the system is able to save 16.92% in the energy cost and decrease electricity and natural gas demand standard deviations by 8.34% and 66.64%, respectively.

Evaluation of hydrogen storage technology in risk-constrained stochastic scheduling of multi-carrier energy systems considering power, gas and heating network constraints

“…A twostage model for combined gas and power networks is proposed in [18] by studying the uncertain parameters. The authors have proposed an innovative energy management model in [19] for smoothening gas and power load patterns by taking advantage of interconnection among power and gas networks and technologies such as the power to gas and CHP units.…”

“…Equations ( 17) and (18) show the limitation of the conversion of power to hydrogen and hydrogen to gas. Equation (19) shows the amount of energy available in the hydrogen storage system.…”

Cooperative energy management of multi-energy hub systems considering demand response programs and ice storage

“…In the cooperative methods, the objective is to find the Pareto optimal solution of the problem, but finding the equilibrium point is the objective in the non-cooperative models. The authors in [12] proposed a cooperative model including power to gas (P2G) devices for integrated power and gas networks and considered the demand smoothness and cost reduction in the network. Nevertheless, the effect of cooling system, demand response program, and fair allocation of costs are not investigated.…”

Robustness Assessment of Hetero-Functional Graph Theory Based Model of Interdependent Urban Utility Networks

“…It was found that strategic coordination would aid in addressing several practical challenges in natural gas systems, including natural gas leakage [16], rapid changes and significant uncertainties in gas demand [15], and natural gas-supply bottlenecks [6], etc. Additionally, integrated gas-electricity planning and operation is helpful in tackling the challenges frequently witnessed in electric power systems, such as (1) the substantial gap between peaks and valleys of demand profiles [17], (2) the inherently stochastic characteristics of renewable production [18], (3) the poor performance of electricity demand prediction [19], etc. Furthermore, the unwillingness of both natural gas and electricity system operators to share proprietary information is taken into account in numerous studies.…”
