Power supply system of industrial parks. [...] Battery energy storage technology is an important part of the industrial parks to ensure the stable power supply, and its rough charging and discharging mode is difficult to meet the application requirements of energy saving, emission reduction, cost reduction, and efficiency increase.
Generally speaking, traditional planning for power supply systems in industrial parks mainly consists of two aspects, i.e., load forecasting and power transmission network design.
Furthermore, an optimal allocation method of a multi-energy power supply system in industrial park is established, taking minimum total cost as the optimization objective, which is then solved by the hybrid genetic algorithm and pattern search algorithm.
Compared to conventional power supply system in industrial park, where it is only supplied by utility grid, the current power supply system becomes a more complex one with integration of multiple DGs such as wind turbine (WT), photovoltaic (PV), diesel, fuel cell, gas turbine and micro turbine , .
Parameters setting In this section, an industrial park power supply system is adopted as a test case. Table 1 summarizes the system parameters used in this case study, including the WT generation system, PV generation system, and BESS.
A correction is made to avoid imbalance of energy shifting and over demand response. Two indexes are proposed to characterize the complementary of multi-energy. The optimal allocation method can greatly reduce electric energy supply cost. Industrial Park is one of the important scenarios of distributed generation development.
