An optimization method for economic operation of a multi-energy power supply system comprises the specific steps of: acquiring historical data of photovoltaic power generation, wind power generation and user loads, and predicting photovoltaic power generation, wind power generation and user load power in each hour period in one day through using an adaptive weight particle swarm optimization algorithm with process regulation factors; constructing a power supply cost model of the multi-energy power supply system; constructing an operation constraint condition of each unit of the multi-energy power supply system; and taking the lowest power supply cost as an objective function, selecting the output power of a diesel engine generator and the charging and discharging power of an energy storage system as optimization decision variables, taking the operation constraint condition of each unit of the multi-energy power supply system as a limit, randomly generating an initial population, and searching an optimal solut
