[0130] Input configuration: Consider the economics of daily scheduling, convert the total equipment cost into daily equipment cost, and purchase electricity from the main network in time-sharing. The time division of time-of-use electricity price is as follows: peak hours are: 10:00-15:00, 18:00-21:00; normal hours are 07:00-10:00, 15:00-18:00 and 21:00: 00-23:00; valley hours are 00:00-07:00, 23:00-24:00. The electricity purchase price during peak hours is 0.83 yuan / kW·h, the electricity purchase price during normal hours is 0.38 yuan / kW·h, and the electricity purchase price during valley hours is 0.17 yuan / kW·h. If the energy storage device still has a surplus after meeting the load demand, and at the same time, in order to ensure the initial state of the next cycle of electricity storage, it will sell electricity to the grid at a price of 0.3 yuan / kW·h. The specific data are as follows Table 1 and Table 2 are shown. The natural gas generated through P2G is sold to the gas...

The invention discloses an electricity storage and gas storage capacity configuration and scheduling optimization method including a P2G microgrid. According to the microgrid operation model including P2G units, an electricity storage and gas storage configuration model and a scheduling model are constructed. The electricity and gas storage configuration model adopts particle The group optimization algorithm configures the rated capacity of the power storage device and the gas storage device, and the scheduling model adopts the differential evolution algorithm to take the lowest daily operating cost of the microgrid as the objective function to charge and discharge the power storage device, and charge and discharge the gas storage device. Power, electricity sales power, electricity purchase power, load transfer power and input power of P2G equipment are adjusted, and the objective function value is returned as the fitness value to the power storage and gas storage configuration model, and then the power and gas storage device is optimally configured according to the fitness value . The present invention is applicable to the configuration strategy of electricity storage and gas storage and micro-grid optimization scheduling under the multi-scenario operation of the micro-grid including P2G, and improves the utilization efficiency of energy while reducing the unreasonable configuration cost of electricity storage and gas storage.
Description
technical field [0001] The invention relates to a power storage and gas storage capacity configuration and scheduling optimization method including a P2G microgrid, and belongs to the technical field of power system operation scheduling. Background technique [0002] Traditional fossil energy power generation will not only cause the continuous consumption of non-renewable energy, but also bring a certain impact on the environment. Therefore, the development of new energy power generation is an irreversible trend, the most typical is the use of photovoltaic power generation. According to statistics, my country's photovoltaic installed capacity in 2019 is 30.1GW. Under the background of large-scale photovoltaic access to microgrids, it not only makes it difficult to accommodate photovoltaics in distribution networks, but also affects the security and stability of microgrids. The light abandonment phenomenon is more serious. On the premise of ensuring the safety and stability ...
