Integrated Demand Response For Microgrid With Combined Heat And Power System

The aim of this study is to form a collaborative operation of photovoltaic thermal(PV/T)-based prosumers and a microturbine-based CHP system by considering the electricity and heat requirements of our contemporary buildings。The proposed work focuses on the integrated demand response(DR)activity of the prosumer that encompasses the changing preferences of the user towards electricity as well as heat energy consumption with time.This has been done to analyze the economics of the two main entities of the network i.e.prosumer and microgrid operator(MGO).The price-based demand response scheme is considered for the sake of optimally managing the bidirectional flow of electricity and heat model.Moreover,the thermal storage unit is exploited in close coordination of the auxiliary boiler to thwart the considerable amount of heat losses,which in turn helps to improve the system’s reliability that is generally compromised due to any contingency or disruption of microturbine operation.The profit maximization problem is designed as our objective functions for both the prosumer and microgrid operator(MGO),and their mutual interaction with each other establishes on the basis of demand response.Such an interaction requires the strategic decision-making process,which is then accomplished by the use of a Stackelberg Equilibrium(SE)game also knows as the leader-follower game.The MGO acts as a leader whereas the PV/T prosumers act as a follower.As the coordination of two players in a game is a problem of non-linear optimization,the Differential Evolution(DE)algorithm is used for the solution of this problem.Finally,a case study has been done to prove the supremacy or advantages of the proposed model by comparison of the results obtained after a simulation.
