    • The present invention relates to a heat source for heating or an electricity generation system using waste heat, and a control method thereof. The heat source or the electricity generation system includes: an absorption heat pump (100) which is supplied with a driving heat source and heat source water to raise the low temperature of a thermal medium by heat of absorption and heat of condensation and then discharges the thermal medium; a heat exchanger (21) for a regenerator to supply the driving heat source to a generator (110) by the waste heat; a heat exchanger (220) for an evaporator to supply the heat source water to an evaporator; a thermal medium circulation line (310) of a closed loop form for circulating the thermal medium of which the temperature is raised through an absorber (140) and a condenser (120); a power generation unit (400) which is branched from the thermal medium circulation line (310), is indirectly heat-exchanged with hot thermal medium to drive a steam turbine (430) by a Rankine cycle, and thus generates electricity; a heat generation unit (500) which is branched from the thermal medium circulation line (310) and is indirectly heat-exchanged with the hot thermal medium to supply the heat source for heating to a location with a heat need; and a switching valve unit (600) provided in the thermal medium circulation line (310) to selectively control the flow of the thermal medium to the power generation unit (400) or the heat generation unit (500). The electricity can be generated in seasons when demands for the heat source for heating are little, thereby utilizing the waste heat generated from the power generating equipment or industrial equipment and thus improving the efficiency of waste heat recovery.
